Summary form only given. Over the last five years, the performance of semiconductor optical amplifiers (SOAs) has improved considerably. In this paper, the parameters of importance for characterizing SOAs are introduced and their significance in characterizing fiber links performance are pointed out. In particular, the gain, the concept of signal-to-noise ratio at the input and output of the amplifier, the overall noise figure of an SOA, the saturation power, the electrical and optical signal-to-noise ratios are discussed. This paper also demonstrate how SOAs can get around the thermal noise limit of standard optical p-i-n detectors/pre-amplifiers and reach an optimal sensitivity of 44.5 photons per bit at a bit-error-rate (BER) of 1 /spl times/ 10/sup -9/, despite the degradation caused by spontaneous-emission noise.

Recent advances in commercial-off-the-self (COTS) fiber optic transceivers have provided attractive new opportunities for avionics system designers to utilize this new generation of COTS transceivers to develop advanced avionics systems which have stringent requirements for high performance, light weight and low maintenance costs. On the other hand, COTS transceivers are generally not designed specifically to meet avionics environmental requirements. Avionics system designers are facing with a new challenge in selecting the best COTS transceivers, which meet the system cost and performance objectives. Before starting a rigorous qualification test process, a strategy to down select COTS transceivers for specific avionics systems is to utilize extended temperature range testing to identify robust COTS transceivers for avionics system applications. In this paper, we describe some of the extended temperature characterization results for COTS bi-directional (BiDi) transceiver at 125 Mb/s.

In this paper, we present the low-cost optoelectronic transceiver developed by D-Lightsys for short reach optical communications applications within severe environments such as avionic, space and defense. In particular the transceiver operates on the [-40;+85/spl deg/C] temperature range and withstands temperature excursions up to 125/spl deg/C. The transmitter (Tx) and receiver (Rx) part of the module are operating from a few Mbps to 3.3 Gbps.

Integrated holographic en/decoders are proposed to provide wavelength-hopping time-spreading codes for optical-code division-multiple-access avionic systems. A prototype device employs two holographic Bragg reflectors to perform data en/decoding with two complementary diagonal 16-chip temporal-spectral codes.

The loss of coax, even moderately high frequencies, can be so high as to rule out many important applications. Lower loss means RF transmission exist, such as waveguides, but the size and weight of such options severely restrict the applications. In this paper, the authors review the conditions under which an optical link can achieve positive gain, as measured by the available power gain. This paper also reviews the link design factors that permit the link to have low noise figure and show that there is a fundamental dependence link gain and noise figure.
