OSA Journal Style Guide


Additional information and templates for MS Word and LaTeX are also available. The online style guide below also provides details on manuscript preparation. Download OSA's "Publishing Your Manuscript" brochure or presentation to receive tips for preparing a manuscript and an overview of the peer review process.

1. Layout and title page elements

Page layout for MS Word should be as follows for estimating final length: Body text: 10-pt Times New Roman. Paper size, U.S. letter. Margins should be set for a 3.3-cm (1.3 in.) top and bottom and 4.11-cm (1.625 in.) left and right. The LaTeX style file will provide proper layout for TeX files.

The title, author listing, and all section headers should be in Arial font. The rest of the text and body of the article should Times New Roman.

The title should be concise but informative. Avoid beginning with an article, a preposition, or the words "first," "new," or "novel." Titles may be edited by the publisher to facilitate computer search. Use initial cap for first word in the title or for proper nouns. Use lowercase following colon. The title should be left aligned and in 16-pt. bold Arial font. Kerning should be set to 16-pt. and spacing expanded by 0.5 inch.

Author names should be given in full and consistent form to facilitate indexing. Every effort should be made to keep author names consistent from one paper to the next as they appear within OSA publications. All authors must be grouped together using superscripts to call out each affiliation. Left align author names in 12-pt. bold Arial font using small caps. Only one corresponding author should be indicated in the affiliations. Otherwise, do not indicate a corresponding author with an asterisk. If necessary, provide email addresses for multiple authors who share responsibility as the contact post-publication.

Affiliations and postal addresses for all authors should appear on the title page. All authors must be grouped together using superscripts to call out each affiliation. Hard returns (Enter key) must be used to separate each individual affiliation. If all authors share one affiliation, superscript numbers are not needed. The corresponding author will have an asterisk indicating footnote. Abbreviations should not be used. E-mail address for the corresponding author should be given.


The abstract should be limited to approximately 100 words. It should be an explicit summary of the paper that states the problem, the methods used, and the major results and conclusions. If another publication is referenced in the abstract, abbreviated information (e.g., authors, journal, volume number, first page, year) must be given in the abstract itself without a reference number. The first reference cited in the main text will be [1]. Note that the combination of abstract and title must be an adequate indicator of the content of the paper, since it will stand alone in electronic bibliographic databases.

Section headings are not necessary for Letters or Memoranda. The styles for the three levels of headings are as follows with some variation among journals:

1.1. Subsection
1.1 Subsection 2

Sections should generally follow the conventional order: Introduction, Method, Results, Discussion, and Conclusion. Do not include Methods in a separate section at the end.

2. Mathematical and scientific notation

2.1 Math

Authors must identify equations and figures in the text by inserting Fig. or Eq. before the number. Display equation numbers should appear in parenthesis [Eq. (1)]. All equations should be created in MathType (Microsoft Equation Editor 3.0 users are encouraged to use MathType now that Microsoft no longer supports the Equation Editor). The express journals do not accept equations built using the Word 2007 or 2010 Equation Builder. All display equations should be created in MathType. Inline equations can be created with these tools or by using keyboard and Unicode characters where needed for the best quality line spacing. Numbered display equations can be labeled manually or with MathType's numbering feature. For TeX, use of standard LaTeX or AMSTeX commands will greatly facilitate production. Please keep all notation and formatting as simple as possible.

2.2 In-line math

Simple fractions in in-line math should use parentheses when necessary to avoid ambiguity, for example, to distinguish between 1/(n - 1) and 1/n - 1. In-text fractions should be set on line, not built up. Exceptions to this are proper fractions such as ½, which are better left in this form. Summations and integrals that appear within text such as Δ n = n 2 should have limits placed to the right of the symbol to reduce white space and should not use oversized symbols.

0 2 π exp [ i k ρ r B cos ( ϕ θ ) ] exp ( i n ϕ ) d ϕ = i n 2 π J n ( k ρ r B ) exp ( i n θ ) , (1)

2.3 General guidelines on notation

Notation must be legible, clear, compact, and consistent with standard usage. In general, acronyms should be defined at first use. Adherence to the following guidelines will greatly assist the production process:

Exponentials. Avoid tiny superscripts of exponential e (e.g., ejkl) by using the alternative exp notation, exp(jkl).

Variables and Vectors. Set single-letter variables in italics (k). Set three-vectors in boldface (k). Functions, derivative "d," abbreviations, and multiletter identifiers should be set in roman (plain) type α cos ,   ... d x ,   k out .

Multiplication. In general, close up multiplied terms (pypx); use × if multiplication sign is essential (1 × 10 2) or for continuation in displayed equations [see Eq. (2) above]. Use raised dot only for scalar product (k · k).

Fences. For simple bracketing the usual order of parentheses and brackets is { [ ( { [ ( · ) ] } ) ] } .

Bit and Byte. The standard abbreviations for bit and byte are b and B, respectively. To avoid confusion, these units should be spelled out in most cases (1 bit, 20 GByte).

Metric System. The metric system is used in OSA journals. If nonmetric units are essential (e.g., for parts specifications), conversion should be given at first mention:  ". . . a ¼-in. bolt (1 in. = 2.54 cm)."

3. References and notes

References and Notes should be numbered consecutively in the order in which they are first referenced in the body of the paper. Two references [2,3] should be included together, separated by a comma, and three or more consecutive references should be indicated by the bounding numbers and an en dash [1–4].

Each source must have its own reference number.

When on-line reference numbers are essential (e.g., see [1]), it is not necessary to use the words "Reference(s)" or "Ref(s)." except when needed for clarity. Footnotes (notes at the bottom of text pages) are not used in OSA journals. Footnotes should be incorporated into the text or set with references as an endnote.

Do not use "et al." in your references. When citing authors in the body of the text, you can use "et al."

Here are some examples of how to set the most common reference types:

Journal paper

For journal articles, authors are listed first, followed by the article's full title in quotes, the journal's title abbreviation, the volume number in bold, the issue number in Roman and parenthesis, inclusive page numbers, and the year in parentheses. Journal titles are required. Do not include web addresses in published journal citations—these will be added post-publication.

4. Funding

Funding information should be listed in a separate block preceding any acknowledgments. The section title should read "Funding" in 10-pt. bold Arial font. The section title should not follow the numbering scheme of the body of the paper. List just the funding agencies and any associated grants or project numbers, as shown in the example below:

National Science Foundation (NSF) (1253236, 0868895, 1222301); Program 973 (2014AA014402); Natural National Science Foundation of China (NSFC) (123456).

OSA participates in Crossref's Funding Data, a service that provides a standard way to report funding sources for published scholarly research. To ensure consistency, please enter any funding agencies and contract numbers from the Funding section into Prism during submission. Update any changes to your funding information in Prism during any revision stages.

5. Acknowledgments

Acknowledgments should be included at the end of the document. The section title should read "Acknowledgments" in 10-pt. bold Arial font. The section title should not follow the numbering scheme of the body of the paper. The body of the section should follow the font and layout of the body of the paper. Please do not include any funding sources in the Acknowledgment section.

6. Disclosures

A Disclosures statement will be required for all submissions beginning 1 September 2019. Authors, reviewers and editors for the Journal of Optical Communications and Networking (JOCN) may voluntarily comply with the guidelines, but the Disclosures statement is not required for JOCN. Disclosures should be listed in a separate section at the end of the manuscript. The section title should read "Disclosures" in 10-pt. bold Arial font. The section title should not follow the numbering scheme of the body of the paper. List the Disclosures codes identified on OSA's Conflict of Interest policy page, as shown in the examples below:

ABC: 123 Corporation (I,E,P), DEF: 456 Corporation (R,S). GHI: 789 Corporation (C).

If there are no disclosures, then list "The authors declare no conflicts of interest."

7. Figures, supplementary materials, and tables

7.1 Figures

Figures should be included directly in the document. All figures and tables must be called out in the text in the order they appear. All photographs must be in digital form and placed appropriately in the electronic document. All illustrations must be numbered consecutively (i.e., not by section) with Arabic numbers. The size of a figure should be commensurate with the amount and value of the information conveyed by the figure.

Authors must use one image file per figure. Figures must be inserted as objects that are fixed and move with the text, not as floating objects. Figures should never be placed in a table environment. All the figures should be centered, except for small figures no wider than 2.6 in. (6.6 cm), which may be placed side by side. Place figures as closely as possible to where they are mentioned in the text. No part of a figure should go beyond the text margins. The figure should not be embedded inside the text.

All figure captions should be centered beneath the figure. Longer figure captions should be centered beneath the figure and alignment double (left and right) justified, but are not to exceed the left and right edge of the figure by more than 0.5 in. The abbreviation "Fig." for figure should appear first followed by the figure number and a period. Captions should be in 8-pt. font. At least one line of space should be left before the figure and after the caption.

Copyright and permissions

If any figures have been previously published, it is important that authors request permission from the publisher (not from the author) and add the required permission line to the caption exactly as specified by the publisher. Use of images under an open license often still requires attribution. Please check the source for applicable terms for reuse. Note that images of people or images owned or trademarked by other entities (including well-known logos or cartoon characters for example) will also require official written permission for publication in OSA journals. Copies of all permission grants should be forwarded to the journal.

Use of the Lena image in OSA Journals

Authors are encouraged to avoid use of the Lena image. Authors who submit manuscripts to OSA journals that include the Lena image will be asked to justify the scientific necessity of using the image and why no reasonable substitute can be made. Authors are encouraged to use alternate test images. Other standard test images include, "Cameraman" or "Mandrill" or "Peppers" or a large number of other images distributed with packages like MATLAB and available in the public domain.

7.2 Supplementary materials in OSA journals

Most OSA journals allow authors to include supplementary materials as integral parts of a manuscript. Such materials are subject to the same editorial standards and peer-review procedures as the rest of the manuscript. Authors who wish to submit supplementary materials must adhere to Author Guidelines for Supplementary Materials in OSA journals. Note that, with the exception of Optica, OSA journals require supplementary material consisting of additional text, figures, tables, equations, etc., to be included as an appendix to the manuscript and not as separate supplementary files.

To ensure consistent presentation, broad accessibility, and long-term archiving for multimedia files, please follow these guidelines on presentation.

(a), (b), (c) phase retrieved without iterative refinement using 1, 2 and 4 distances respectively; (d), (e), (f) phase retrieved with 10 iterations' refinement using 1, 2 and 4 distances respectively (see Visualization 1, Visualization 2, Visualization 3, and Visualization 4). [Sample figure adapted from Opt. Express 26, 1110 (2018).]

Video files must use open compression standards for display on broadly available applications such as VLC or Windows Media Player. MOV, AVI, MPG, and MP4 video containers are accepted.

The following multimedia guidelines will help with the submission process:

  • 15 MB is the recommended maximum multimedia file size.
  • Minimize file size by using an acceptable codec such as x264 or XviD. HandBrake is an open source tool for converting video to common codecs.
  • 720 x 480 pixels (width by height) is the recommended screen size.
  • If appropriate, insert a representative frame from the video in the manuscript as a figure.
  • Videos must be playable on all platforms using VLC.
  • Animations must be formatted into a standard video file.

Please refer to Author Guidelines for audio, data files, code, and large datasets.

7.3 Tables

Tables should be centered and numbered consecutively. Authors must use Word's Table editor (or appropriate LaText markup) to insert tables. Authors must not import tables from Excel. Tables with multiple parts should be split into separate numbered tables [not Table 1(a), Table 1(b), etc.]. Tables should use horizontal lines to delimit the top and bottom of the table and column headings. Detailed explanations or table footnotes should be typed directly beneath the table, but not in a table cell. Table footnote labels should be text; numbers or special characters are not permitted. Position tables as closely as possible to where they are mentioned in the main text.


8. Article thumbnail upload

OSA authors are strongly encouraged to upload a thumbnail image to be used next to their article in the Table of Contents and abstract pages of the journal. Authors must submit a .JPG file. The image will be resized to 100 × 100 pixels. For best results, authors should upload an image this size or an image with square dimensions. No author photos are to be submitted; exceptions must be cleared by the Managing Editor.

The 100 × 100 pixel image will be displayed on the article abstract page, and a 50 x 50 pixel image will be displayed on the Table of Contents page.

Although a replica of the image does not need to appear in the manuscript itself, it must have a strong connection to the research contained within the paper and must be the property of the author(s) of the current paper. This means that even if the article does not contain figures, a thumbnail can still be submitted as long as it relates strongly to the research and is original. Images containing institution or corporate logos should not be submitted.

9. Summary

Conforming to the specifications listed above is of critical importance to the speedy publication of a manuscript. Authors should use the following style guide checklist before submitting an article.


10. Quality of English

If a student-level reader might find your English difficult to understand, please have a colleague who is fluent in English edit your paper or consider using a language editing service (e.g., http://languageediting.osa.org/) before you submit it to OSA. A poorly written manuscript will most likely be rejected without external review, so addressing language deficiencies before submission is important.

11. Letter Paper Length

Note that Optics Letters and letters papers in Optica have a limit of four printed pages. Optica memoranda have a two-page limit. If a paper exceeds this limit, it must be shortened before the paper is accepted. If the page proof is over the four-page limit, the proof must be shortened before the paper can be assigned to a final issue. Authors should use the appropriate Legacy Word or LaTeX templates to prepare Letters and Memoranda to facilitate length checking.

12. Final Remarks

Authors will receive an e-mail notification to download page proofs of their papers. Corrected proofs should be returned following the instructions in the notification as soon as possible, preferably within 24 hours of receipt, to avoid publication delays.
