We simulated 8 400-Gbit/s PDM-QPSK over 2000-km transmission by using Map detection to reduce the channel spacing to 100-GHz. MAP detection can significantly improve the system performance to < 10−3 BER compared to non-MAP detection.
We proposed a PMD monitoring/compensation method in frequency domain for coherent system. With 15 ps of average DGD, the PMD induced penalty for 100-Gbit/s QPSK system is reduced by 9 dB at symbol-error-ratio of 10−3.
We demonstrated the QPSK signal generated by a single phase-modulator (PM-QPSK) is more tolerant to fiber nonlinearity than that generated by the Mach Zehnder Interferometer (MZI-QPSK). Simulation of WDM system at 28-Gsymbol/s per polarization shows PM-QPSK outperforms MZI-QPSK in coherent systems when polarization multiplexing and dispersion management is used.
We have investigated the Bragg gratings for surface plasmonic polaritons modes in the metal-dielectric-air waveguide and proposed a bidirectional coupler which is capable to guide the incident light at different wavelengths along two predetermined directions.

In this paper, we present a theoretical discussion of the design of bidirectional wave couplers based on plasmonic Bragg gratings in the near infrared domain. A key feature in the design of the plasmonic Bragg gratings is the dependence of the effective refractive index on the thickness of the dielectric layer. These gratings, which function as band rejection filters, enable directional coupling of...
