Dual Polarization Nonlinear Frequency Division Multiplexing Transmission [PDF]
IEEE Photonics Technology Letters, 2018 We experimentally demonstrate dual-polarization nonlinear frequency division multiplexing (NFDM) using the continuous spectrum in 1680 km of normal dispersion fiber, at the net data rate of 25.6 Gb/s. NFDM exhibits a gain of 0.4 dB in $Q$ -factor and 1 dB in total launch power when compared with burst mode OFDM.

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 ...

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.
