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.

Direct-detection polarization division multiplexed orthogonal frequency-division multiplexing transmission systems without polarization tracking

Optics Letters, 2012
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 ...

Modelling of a polarization-division multiplexing soliton transmission system

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.

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.

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 ...

Direct-Detection Receiver for Polarization-Division-Multiplexed OOK Signals

IEEE Photonics Technology Letters, 2015
We propose a direct-detection receiver capable of detecting polarization-division-multiplexed (PDM) ON-OFF keying (OOK) signals without using a dynamic polarization controller. The proposed receiver, consisted of a polarization-beam splitter, three $1\times 2$ directional couplers, three photodetectors, three analog-to-digital converters, and a ...

Power unbalanced polarization-division-multiplexing for efficient bandwidth utilization

Technical Digest. Summaries of papers presented at the Conference on Lasers and Electro-Optics. Postconference Edition. CLEO '99. Conference on Lasers and Electro-Optics (IEEE Cat. No.99CH37013), 2003
Summary form only given. There has recently been a capacity explosion of optical fiber links due to techniques such as WDM. However, WDM high-capacity systems are straining to accommodate either smaller channel wavelength spacing or wider wavelength range in order to continue the growth in capacity.

Nonlinear phase noise in polarization-division-multiplexed DPSK systems

2006 Conference on Lasers and Electro-Optics and 2006 Quantum Electronics and Laser Science Conference, 2006
Nonlinear phase noise (NPN) in polarization-division-multiplexed DPSK systems is analyzed. It is found that the absolute NPN is inversely proportional to the square-root of channel spacing, while the differential NPN depends on the launch condition.

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.

Optical labeling technique using wavelength-offset polarization division multiplexing

2006 Conference on Lasers and Electro-Optics and 2006 Quantum Electronics and Laser Science Conference, 2006
An optical labeling technique using wavelength-offset polarization division multiplexing (PDM) is proposed and demonstrated. Unlike the conventional PDM technique, the proposed technique can suppress the effects of crosstalk induced by polarization variation.
