Abstract

A novel approach to achieving a polarization-insensitive semiconductor optical amplifier is presented. The active layer consists of graded tensile strained bulk-like structure, which can not only enhance TM mode material gain and further realize polarization-insensitivity, but also get a large 3dB bandwidth due to different strain introduced into the active layer. 3dB bandwidth more than 40nm, 65nm has been obtained in the experiment and theory, respectively. The characteristics of such polarization insensitive structure have been analyzed. The influence of the amount of strain and of the thickness of strain layer on the polarization insensitivity has been discussed.
