Abstract

A semiconductor optical amplifier is a key device for optoelectronic integrated circuits (OEICs). Such an amplifier could be used as preamplifier, in-line amplifier, booster amplifier, and switch. Recently, semiconductor optical amplifiers with buried facets have been demonstrated.1 We discuss here the operation of a semiconductor optical amplifier, which is provided with tilted buried facets. A 28 dB peak gain with less than 1 dB gain ripple and less than 1 dB TE-TM gain difference is achieved.
