Polarimetric current sensor based on polarization division multiplexing detection
Optics Express, 2014 A polarimetric current sensor based on polarization division multiplexing (PDM) detection is proposed. The novel sensor head with a heat insulation cavity only induces a small level of birefringence. Comparing with polarization diversity (PD) detection, the sensitivity of PDM detection is the double of PD detection.

A Highly Flexible Polarization Demultiplexing Scheme for Short-Reach Transmission
IEEE Photonics Journal, 2015 We propose and experimentally demonstrate an effective and highly flexible polarization demultiplexing scheme based on a Stokes analyzer, which could be also applied to the nonorthogonal polarization division multiplexing (NPDM) schemes.

Automatic optical polarization demultiplexing for polarization division multiplexed signals
Optics Express, 2009 We propose a new automatic optical polarization demultiplexing scheme for polarization division multiplexed (PDM) signals, which uses the radio frequency (RF) power from a low frequency RF power detector as a control signal. This scheme is based on the intrinsic characteristics of PDM signals and does not need to add a special signal at a PDM ...
