Abstract

A broadband wavelength-parallel polarimeter has been designed for polarization measurements of multiple Dense WDM channels in parallel, which is based on a 2-D spectral disperser via a diffraction grating and a virtually-imaged phased-array (VIPA). At a hyperfine 2.8 GHz subchannel spacing, we have demonstrated spectral polarization measurements of ~1500 sub-channels (~32 nm spectral range), with a potential total measurement time of less than 5 ms.

(b) Measured SOP data of 2 neighboring FSRs of the VIPA output, equivalently 100GHz spectral range. (c) Measured SOP data of all 82 FSRs. Note: the reason the PSP axis of the PM fiber is not aligned with linear polarization is because the PSP has been shifted by the single mode fiber (SMF) after the PM fiber.
