Paper Abstract

A broadband width semiconductor optical amplifier is reported using an asymmetric quantum well structure. By applying tensile strain to the quantum wells it is possible to both increase the optical bandwidth while reducing the polarization sensitivity. The effects of the ordering of the asymmetric quantum wells, length of the device and carrier density all affect the performance of the device. Using the asymmetric struture, a 90 nm region of polarization sensitivity less than 1.2 dB within the -3dB band width is achieved.
