2017 5th International Conference on Wireless and Optical Communications (ICWOC 2017) will be held during July 7-9, 2017 in Singapore, and it is sponsored by ACM Singapore Chapter and University of El...
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, ...
Polarization modulation is a robust and efficient format for optical free-space communications. We study the sensitivity of real-world balanced receivers, including possible atmospheric effects on the...
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....
In spite of some setbacks, the last 10 years have seen phenomenal advances and growth in optical systems/networks. From a commercial viewpoint, deployed transmissions systems have per fiber capacities...
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...
Based on the structure proposed in [1] and [2],two new types of parallel decision feedback loops are presented. Efforts are made to secure the data transition and relax the delay limitation for the in...
