Paper Abstract

Optical preamplification has been shown to significantly improve the sensitivity of receivers for wideband lightwave systems when compared with conventional electronic postamplification. However, the large size and relatively fragile nature of optical preamplifiers assembled from discrete optoelectronic components (i.e., hybrid assemblies) has discouraged the use of optical preamplifiers for system applications. This paper discusses the technology required for integrating a semiconductor optical amplifier with a high-speed photodetector on the same chip, [1] and the expected performance of such a device. The monolithically Integrated Optical Preamplifier (lOP) is expected to combine the performance of hybrid receivers with the functionality of a single optoelectronic component. In addition, this integrated device can be used as a lossless optical tap for network monitoring and/or system reconfiguration, functions that are highly desirable for advanced network architectures.
