Cross-Polarization Modulation in Polarization-Division Multiplex Transmission
IEEE Photonics Technology Letters, 2010We show theoretically and with the aid of computer simulations that the nonlinear depolarization induced by cross-polarization modulation leads to crosstalk between the polarization-division multiplex (PolDM) subchannels during their demultiplexing. This additive crosstalk can be approximated as additive Gaussian noise, and we derive expressions to ...

Multifunction Lidar System Based on Polarization-Division Multiplexing
Journal of Lightwave Technology, 2019A multifunction lidar system is proposed based on polarization-division multiplexing, by which the distance, velocity, and depolarization ratio of a target can be simultaneously measured. The key component of the lidar system is a polarization-division multiplexing dual-drive Mach-Zehnder modulator (PDM-DMZM).

Multiple soliton interactions in a polarization–division multiplexing system
Optics Communications, 1998Abstract We numerically study multiple soliton interactions in a polarization–division multiplexing transmission system. It is found that, unlike the transmission system of solitons with the same polarization, the two soliton interaction is not the strongest compared to the interaction of more than two solitons.

Robust Carrier Recovery in Polarization Division Multiplexed Receivers
Optical Fiber Communication Conference, 2012We present a novel carrier recovery which can track fast and large sinusoidal frequency oscillations of commercially available lasers and efficiently compensate for laser noise. Q gain of 0.8 dB is recorded in offline experiments.

Manipulating Polarization-division Multiplexed Terahertz Signals with Four-wire Waveguides
Proceedings of the 2022 Conference on Lasers and Electro-Optics Pacific Rim, 2022We demonstrate a new metal-wire waveguide topology, namely a four-wire waveguide, which simultaneously acts as a broadband terahertz polarization-division multiplexer and a novel platform to realize the independent manipulation of polarization-division multiplexed terahertz signals.

Polarization-division multiplexing based multi-function lidar system [PDF]
2018 23rd Opto-Electronics and Communications Conference (OECC), 2018 We demonstrate a flexible multi-function lidar system based on polarization-division multiplexing (PDM), in which simultaneous ranging and velocimetry are achieved. With slight modifications, the lidar system can also be used for other functions.

Nonlinear phase noise in polarization-division-multiplexed DPSK systems
2006 Conference on Lasers and Electro-Optics and 2006 Quantum Electronics and Laser Science Conference, 2006Nonlinear phase noise (NPN) in polarization-division-multiplexed DPSK systems is analyzed. It is found that the absolute NPN is inversely proportional to the square-root of channel spacing, while the differential NPN depends on the launch condition.

Visible light communications: increasing data rates with polarization division multiplexing
Optics Letters, 2020In this Letter, we propose a new configuration for visible light communication systems, which results in doubling of the data rate due to the use of polarization division multiplexing. As light-emitting diodes are unpolarized incoherent light sources, we isolate both the perpendicular s and parallel p modes for

Polarization division multiplexing for nonlinear Fourier-based transmission schemes
Conference on Lasers and Electro-Optics, 2018A polarization-division multiplexing (PDM) transmission scheme based on the nonlinear Fourier transform (NFT) is considered. A new dual-polarization processing technique with reduced complexity, providing 1dB performance improvement, is introduced.

Measurement Techniques for Determining the Polarization Division Multiplexing Tolerance Field [PDF]
2019 International Conference on Advanced Technologies for Communications (ATC), 2019 Polarization Division Multiplexing is a promising technique for effectively increasing the capacity of optical routes. Its basic advantage is the possibility of being deployed on existing optical routes without the need to replace existing fibres or cables.
