We propose nonbinary-LDPC-coded modulation schemes employing subcarrier-multiplexing and three-dimensional constellations. We improve coding gains of conventional PDM-M-QAM by 2.17dB and 2.92dB, for M...
The first experimental demonstration of nonbinary-LDPC-coded optical transmission is presented. Using DQPSK, we can achieve >8dB and ~10dB net coding gains at the BER of 10 -6 in the absence and prese...
We propose using layered update rule in decoding nonbinary LDPC codes. Only 10-15 iterations suffice for good performance. Also, for the same BER performance, it increases throughput by twofold compar...
Coded modulation schemes for optical transport are reviewed and coding of 4-D constellations is discussed including iterative demapping for soft-detection of polarization-switched QPSK which achieves ...
Through temporal pulse shaping at a repetition rate of 42.7 GHz, this paper demonstrates a simple method with applications in high-speed optical communications for adaptive, multi-type pulse shaping, ...
Ge-on-Si waveguide integrated photodetectors including Metal-Semiconductor-Metal (MSM), vertical PIN and lateral PIN diodes are reviewed.
Waveguide-type quasi-phase matched (QPM) nonlinear-optic devices offer numerous applications in optoelectronics area. Wavelength converters based on QPM difference frequency generation (DFG) have adva...
The 8th International Conference on Optical Communications and Networks (ICOCN 2009) invites high-quality recent research results in the areas of optical devices, components, communications, transmiss...
The optical fiber communications community experienced 30 years of rapid growth from 1970 to 2000, and a severe downturn lasting several years after 2000, but has been rising up again in recent years....
Today’s electronic processing capability means that it is now possible to perform extensive signal processing at the highest commercial data rates. In this tutorial we discuss the design and technolog...
