Multiple soliton interactions in a polarization–division multiplexing system

Optics Communications, 1998
Abstract 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.

Multifunction Lidar System Based on Polarization-Division Multiplexing

Journal of Lightwave Technology, 2019
A 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).

Crosstalk detection schemes for polarization division multiplex transmission

Journal of Lightwave Technology, 2001
Polarization division multiplex (PolDM) is a bandwidth-efficient and sensitive modulation format suitable for upgrading bandwidth-limited trunk lines. We show how control signals for polarization demultiplex can be obtained efficiently. For interleaved return-to-zero (RZ) signals, incoherent crosstalk has to be detected and minimized.

Polarization Division Multiplexing for Optical Data Communications

2019
Multiple parallel channels are ubiquitous in optical communications, with spatial division multiplexing (separate physical paths) and wavelength division multiplexing (separate optical wavelengths) being the most common forms. In this research work, we investigate the viability of polarization division multiplexing, the separation of distinct parallel ...

Effect of frequency sliding and filtering on the interactions of polarization-division-multiplexed solitons

Optics Letters, 1995
I analyze by numerical simulation and perturbation theory the effect of frequency-sliding filters on the interactions between orthogonally polarized solitons. It is found that strong filters may substantially increase the collision distance.

Nonlinear Polarization Scattering in Polarization-Division-Multiplexed Coherent Communication Systems

2011
Polarization-division-multiplexing (PDM) [1–4], which transmits two channels with orthogonal states of polarization (SOPs) at an identical wavelength, was proposed long time ago to double the capacity of fiber-optic communication systems, but it was only until recently that the technique attracted much attention. The increasing demand for communication
