Underwater Optical Communication Link Using Wavelength Division Multiplexing, Polarization Division Multiplexing and Orbital Angular Momentum Multiplexing

Frontiers in Optics 2016, 2016
We report on the direct modulation of blue laser diodes for underwater optical communication utilizing wavelength, polarization and space division multiplexing. Using this scalable architecture, we demonstrate an effective data rate of 10 Gbit/s.

Polarization-Division-Multiplexed Nonlinear Frequency Division Multiplexing

Conference on Lasers and Electro-Optics, 2018
We experimentally demonstrate dual-polarization nonlinear frequency division multiplexing using the continuous spectrum in 1680 km of normal dispersion fiber at a burst rate of 128Gbit/s. The DGD penalties are shown to be negligible.

Polarization division multiplexing with subpicosecond solitons

Conference Proceedings. LEOS '97. 10th Annual Meeting IEEE Lasers and Electro-Optics Society 1997 Annual Meeting, 2002
After introducing perturbation terms to the Manakov equation to account for higher-order dispersion and for the Raman effect, we analyze polarization division multiplexing with subpicosecond solitons. Dispersion-shifted single-mode fibers operating at 1.55 /spl mu/m are considered.

An experiment of de-multiplexing for polarization division multiplexing system by PSO algorithm

SPIE Proceedings, 2010
We report an experiment of de-multiplexing automatically in a polarization division multiplexing system using a DSP based de-multiplexer. The searching algorithm was a modified Particle Swarm Optimization. We successfully demonstrated the de-multiplexing scheme both in a 20-Gb/s PolMux-NRZ-OOK system and a 40-Gb/s PolMux-RZ-DQPSK system.

Cross-Polarization Modulation in Polarization-Division Multiplex Transmission

IEEE Photonics Technology Letters, 2010
We 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 ...

First Demonstration of Polarization-Multiplexing Combined with On-Chip Mode-Division-Multiplexing

Optical Fiber Communication Conference, 2014
Polarization-multiplexed data is transmitted jointly with on-chip 2-mode mode-division-multiplexed data. Error-free operation and 5 dB of power penalty at an aggregate 40-Gb/s data rate are demonstrated, showing potential for pol-mux and mode-division-multiplexing networks on chip.

Cross-polarization modulation in polarization-division multiplexed transmission systems

IEEE Photonics Society Summer Topicals 2010, 2010
We introduce the concept of stochastic degrees of freedom to semi-analytically approximate the distribution of nonlinear degree of polarization reduction values observed in numerical simulations as result of cross-polarization modulation.

Variable Polarization/Frequency Division Multiplexing (VPFDM) for Satellite Communications

IEEE Vehicular Technology Conference, 2006
To realize advanced broadband mobile satellite communications, this paper proposes a new wireless access approach named variable polarization frequency division multiplexing (VPFDM); it assigns the resources created by dual polarization states as well as frequency bandwidth to customers.

Polarization division multiplexed optical eigenvalue modulation

2015 International Conference on Photonics in Switching (PS), 2015
We propose a polarization division multiplexed optical eigenvalue modulation scheme based on the invariant property of eigenvalue associated to Manakov equation. We numerically demonstrate the feasibility of the proposed scheme.
