The design of a polarization de-multiplexer and a polarization mode dispersion compensator (PMDC) for direct-detect polarization division multiplexed (PDM) return-to-zero differential quadrature phase shift keying (RZ-DQPSK) systems are studied in de

The design of a polarization tracker and a PMDC for direct-detect RZ-DQPSK PDM systems is reviewed. The error signals are analyzed and their application spaces are identified. Experimental results are demonstrated to verify the designs.

Filter shape and bandwidth are studied for multiplexers/demultiplexers in DQPSK systems. Simulation shows both factors have strong impact on signal performance. In 50GHz spaced systems with 44Gb/s RZ-DQPSK signals, 2nd-order super-Gaussian filters ou

A PMDC working in the cancellation mode is proposed for Pol-Mux RZ-DPSK/ DQPSK systems. It has separate control loops for PMDC and Pol-Demux. It showed 18ps of DGD tolerance in a 112Gb/s bit-aligned Pol-Mux RZ-DQPSK system.

A novel ultra-fast quasi-analytical method capable of directly computing BER in terrestrial WDM systems within few minutes is presented and validated. The modeled BER results remarkably agree with 40 Gb/s duo-binary WDM testbed measurements.
