Abstract

We show proof of concept of a transmission-mode wavelength filtering device consisting of layered holographically formed polymer dispersed liquid crystal (H-PDLC) cells. H-PDLC cells were fabricated from a thiolene based polymer composite to have transmission notches in the near-IR wavelength range. Wavelength filtering was achieved by stacking four H-PDLC cells with transmission notches spaced at 10 nm intervals. Results show a broad transmission notch spanning the spectral width of the constituent cells. With bias applied to an individual cell within the stack, the transmission notch of the cell inverts and the overall transmission envelope changes shape. Using a transmitted energy sensing device and a lineshape mapping algorithm, spectral content can be determined to a resolution of 0.1  nm for narrow banded signals. Applications for this switchable wavelength filtering device include serial detection of spectral content for telecom data signals or chemical and biological sample identification through absorption or emission spectroscopy.

Schematic diagram of the proposed wavelength sensing device. The optical path is shown as an input signal of undetermined spectral content. The H-PDLC filter stack can selectively transmit and reflect a selected wavelength, while the CCD or intensity detector relays wavelength dependent intensity information to a computer.

Transmission notches of individual H-PDLC cells used in this study. H-PDLC transmission spectra were measured with no bias, and data sets were superimposed. (a) Lower wavelength group. (b) Higher wavelength group.

Spectral response of four H-PDLC cells stacked with NOA65 as an adhesive and index matching fluid. The spectral envelope can be seen as the outline of the four individual transmission notches with intensity loss. Additional superimposed data sets show the spectral response of the envelope as each cell switched.

Stacked spectral response of four higher wavelength H-PDLC cells stacked with NOA65 as an adhesive and index matching fluid. Superimposed data sets show the envelope response to each constituent cell with applied bias.

Percent transmission of a test signal through adjacent cells measured using a photodiode. Each cell was switched to its transparent state when the other was measured. Significance is a unique transmission∕wavelength relationship shown here for each 1   nm increment. Mapping percent transmission to wavelength is critical for determining peak wavelength.
