Abstract

Semiconductor optical amplifiers (SOAs) are attractive for various optical communication systems, due to high gain, broad amplification bandwidth, low power consumption, compactness, and so on. Particularly SOAs in array configuration are attractive for application to optical parallel interconnection systems, to compensate optical losses in various stages[1]. However, SOA arrays with high performance as well as uniformity in device characteristics have not been reported, mainly because array compatible SOAs fabrication process has not been established yet. The authors report for the first time 4-channel 1.3pm wavelength polarization-insensitive SOA arrays employing a newly developed MOVPE technique[2].
