All-Optical Signal Regeneration in Polarization-Division-Multiplexing Systems

open access: yesIEEE Photonics Journal, 2011
Schemes of all-optical regeneration in polarization-division-multiplexing (PDM) systems are proposed and demonstrated with 2 × 10-Gb/s return-to-zero on-off-keying (RZ-OOK) transmission. Regeneration is achieved based on self-phase-modulation (SPM)

Automatic optical polarization demultiplexing for polarization division multiplexed signals

open access: goldOptics 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 ...

PMD and PDL impairments in polarization division multiplexing signals with direct detection

open access: goldOptics Express, 2009
We investigate polarization mode dispersion (PMD) and polarization dependent loss (PDL) impairments in polarization division multiplexing (PDM) signals with optical polarization demultiplexing and direct detection. We find that the time alignment between the bits in the two polarizations has a significant impact on the PMD impairments, and PMD ...

Cylindrical vector beam multiplexer/demultiplexer using off-axis polarization control

open access: yesLight: Science & Applications, 2021
The emergence of cylindrical vector beam (CVB) multiplexing has opened new avenues for high-capacity optical communication. Although several configurations have been developed to couple/separate CVBs, the CVB multiplexer/demultiplexer remains elusive due

Polarization-division multiplexing based on the nonlinear Fourier transform [PDF]

open access: yesOptics Express, 2017
Polarization-division multiplexed (PDM) transmission based on the nonlinear Fourier transform (NFT) is proposed for optical fiber communication. The NFT algorithms are generalized from the scalar nonlinear Schr dinger equation for one polarization to the Manakov system for two polarizations.
