Abstract

A new technique is presented for the measurement of the differential group delay (DGD) between principal states of polarization of an optical device, with a demonstrated accuracy and resolution of roughly 50 attoseconds (50 × 10−18 s). Accuracy was directly assessed by measurement of a crystal-quartz DGD Standard. This permits what is to the author's knowledge the first complete measurement of the polarization mode dispersion (PMD) of straight, submeter lengths of optical fiber. PMD can be reliably measured only when the fiber is straight, since spooling of the fiber changes its PMD by introducing additional mode coupling. Measurement of four fiber samples revealed correlation between DGD and fiber core ovality.

Apparatus used for measurement of PMD with Jones matrix eigenanalysis. Jones matrices R and F represent the polarization transformations caused by transmission through SMF1 and the FUT, respectively. After measurement of R1F1 and R2F2 with the FUT in place, the test fiber is removed, the movable arm is repositioned to launch light directly into SMF1, and R1 and R2 are measured. L, lens; P, linear polarizer; WDM, wavelength-division multiplexer; XYZ's, translation stages.

DGD versus position along the fiber for four fibers of various core ovalities. The line segments indicate relative positions of the fiber sections; broken fibers resulted in some missing segments. Fiber A, Corning SMF-28, unknown ovality. Experimental fiber: B, 0.012 ovality; C, 0.093 ovality; D, 0.157 ovality.
