Semiconductor lasers offer promise as high-speed transmitters for free-space optical communication systems. This article examines the performance of a semiconductor laser system in a master-oscillator power-amplifier (MOPA) geometry developed through a Small Business Innovation Research (SBIR) contract with SDL, Inc. The compact thermo-electric cooler (TEC) packaged device is capable of 1-W out...

Generation of millimeter-wave electronic signals and power is required for highfrequency communication links, RADAR, remote sensing and other applications. However, in the 30 to 300 GHz mm-wave regime, signal sources are bulky and inefficient. All-optical generation of mm-wave signals promises to improve efficiency to as much as 30 to 50 percent with output power as high as 100 mW. All of this ...

The outage of optical components like optical amplifiers and cross connects reduces the availability of a network and increases the operational expenditures of network operators. Responsible for this is the repair process of optical components which takes very long, because of the large distances in the field. The detection of performance degradation of erbium-doped amplifiers (EDFAs) can be us...

This paper investigates the impact of a train of input Gaussian pulses wavelength on semiconductor optical amplifier (SOA) gain uniformity for high speed applications. In high speed applications, the linear output gain of the input pulses is necessary in order to minimize the gain standard deviation and power penalties. A segmentation model of the SOA is demonstrated to utilize the complete rat...

Enhanced IPDR performance of a digitally controlled of an SOA is demonstrated for 1, 5 and 10 λ 10Gb/s data. Automated output power control is demonstrated within 0.5dB over a 20dB dynamic range.
