We experimentally demonstrate a direct-detection polarization division multiplexed (PDM) orthogonal frequency-division multiplexing (OFDM) scheme without dynamic polarization tracking. Simply using a polarization-diverse receiver, the proposed multiple-input multiple-output assisted system can achieve bit-error rate of 10(-) over all possible received ...

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 ...

An experiment of de-multiplexing for polarization division multiplexing system by PSO algorithm
SPIE Proceedings, 2010We 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.

Wavelength and polarization division multiplexing using the LP11 mode in a two-mode fiber for mode division multiplexing [PDF]
SPIE Proceedings, 2011 The orthogonality of Mode Division Multiplexing (MDM) with Wavelength division multiplexing (WDM) and Polarization Division Multiplexing (PDM) is investigated applying WDM and PDM transmission over the LP11 mode in a few-moded fiber. Two wavelengths, each carrying 10Gbit/s signals in two orthogonal polarizations are successfully transmitted with the ...

Modelling of a polarization-division multiplexing soliton transmission system [PDF]
Journal of Optics, 1998 We have simulated numerically a polarization-division multiplexing soliton transmission system by using propagation equations with and without the third-order dispersion and Raman shift terms, respectively. It is found that the Raman shift terms can reduce the soliton interactions and hence the allowed transmission distance increases. Resume.

Crosstalk detection schemes for polarization division multiplex transmission [PDF]
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 multiplexed optical eigenvalue modulation
2015 International Conference on Photonics in Switching (PS), 2015We 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.

Optical polarization division multiplexing at 4 Gb/s
IEEE Photonics Technology Letters, 1992An optical polarization multiplexing system using BPSK coherent heterodyne detection to transmit 4 Gb/s over a 45-km standard single-mode fiber optical link at a receiver sensitivity of -35 dBm is described. The 4-Gb/s system has a potential receiver sensitivity of -40 dBm while using 2-Gb/s baseband electronics. >

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.
