Free-space optical communication provides high-capacity data links for defence and security. This conference will provide a forum for all professionals involved with both short and long range free-spa...
Phosphorus, a highly reactive element commonly found in match heads, tracer bullets, and fertilizers, can be turned into a stable crystalline form known as black phosphorus. In a new study, researcher...
Current trends and future challenge in optical communication.
Increasing data bandwidth requirements from spacecraft systems is beginning to pressure existing microwave communications systems. Free-Space optical communications allows for larger bandwidths for lo...
We developed a new ground-to-train free-space optical communication system that performs stable high-speed communication even when a train is running at high speed and does fast handover between laser...
An all-optical polarization temporal signal processor is demonstrated, which performs well in 40-Gbits/s optical signal differentiation with error of ~0.1 and efficiency of ~12%, 80-GHz 3.3-ps optical...
We evaluate PDL-induced penalties in PDM-QPSK coherent systems with both lumped model and distributed model. We find the lumped model significantly over-estimates PDL penalties and PDM coherent system...
We proposed a novel bit-by-bit code-hopping scheme using single phase modulator for secure optical communication and experimentally demonstrated the transmission of 2.5Gbps DPSK data secured by scramb...
Polarization-multiplexed coded-modulation, with joint coherent MAP detection and soft-iterative decoding, which considers independent symbols transmitted over both polarizations as a super-symbol is p...
Current status of optical communication devices based on planar lightwave circuits is described from the technical and marketing points of view. The main market place for optical devices has been shif...
In this paper, the gamma – gamma probability distribution is used to model turbulent channels. The bit error rate (BER) performance of free space optical (FSO) communication systems employing on-off k...
Although research of satellite optical communication system has been carried out for many years, there is scarce literature to comprehensively analyze the influence of space environment on satellite o...
We present a novel, fast method for optimizing the performance of a system. It is used to optimize the dispersion map and signal power in a DQPSK 111Gb/s link.
In this paper, the intrinsic disadvantages of the nowadays low-cost deep-submicron digital CMOS technologies in respect of the design of high-speed optical communication (OC) systems front-end integr...
We report on the development of evanescently coupled waveguide integrated photodetectors in single-ended,differential and balanced configurations, using a flexible monolithic integration scheme on InP...
