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.

All-fiber polarization-division multiplexing to mode-division multiplexing conversion for hybrid optical networks

Applied Optics, 2018
This paper proposes and experimentally demonstrates an all-fiber conversion method that transfers the polarization-division multiplexing (PDM) signals to the mode-division multiplexing (MDM) signals. The conversion scheme is based on a mode converter and a polarization-mode controller.

Gigabit polarization division multiplexing in visible light communication

Optics Letters, 2014
In this Letter, polarization division multiplexing is proposed and experimentally demonstrated for the first time that we know of, in visible light communication systems based on incoherent light emitting diodes and two orthogonal groups of linear polarizers.

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.

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.

Silicon-Based Hybrid (de)Multiplexer for Wavelength-/Polarization-Division-Multiplexing

Journal of Lightwave Technology, 2018
A novel hybrid multiplexer for wavelength-division- multiplexing (WDM) and polarization-division-multiplexing (PDM) is proposed and realized by integrating a polarization-splitter-rotator (PSR) and an optical-filter array based on novel microring resonators (MRRs).

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.

Manipulating Polarization-division Multiplexed Terahertz Signals with Four-wire Waveguides

Proceedings of the 2022 Conference on Lasers and Electro-Optics Pacific Rim, 2022
We 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.

Endless Polarization Stabilizer for High Bit-rate Polarization-Division Multiplexed Optical Systems

OFC/NFOEC 2008 - 2008 Conference on Optical Fiber Communication/National Fiber Optic Engineers Conference, 2008
An endless polarization stabilization method is applied to a 40-Gbit/s RZ-DQPSK polarization-division multiplexed optical system. The effectivness of the polarization stabilizer in allowing the polarization demultiplexing of the two orthogonally polarized channels is experimentally verified.
