Atmospheric pressure MOVPE growth of high performancepolarisation insensitive strain compensatedMQW InGaAsP/InGaAs optical amplifier

Abstract

The authors report a structure for a polarisation insensitive amplifier at 1.55 µm wavelength using 16 compensated strain InGaAsP/InGaAs quantum wells. A high gain of 27 dB for TE and TM modes has been obtained. Polarisation sensitivity less than 1 dB over 85 nm bandwidth has been measured. These results are among the best reported.
