A Highly Flexible Polarization Demultiplexing Scheme for Short-Reach Transmission
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.

Optical router for optical fiber sensor networks based on a liquid crystal cell [PDF]
Optical fiber sensor networks are evolving rapidly. They are used because of the inert nature of optical fibers allowing no electromagnetic interference and safe applications in inflammable atmospheres; other relevant characteristics are their low ...

Polarimetric current sensor based on polarization division multiplexing detection
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.

Automatic optical polarization demultiplexing for polarization division multiplexed signals
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 ...
