Abstract :
It is shown that different TE/TM mode confinement factors in a bulk semiconductor optical amplifier could not be the main reason for the gain anisotropy. Instead, the intrinsic material gain difference for TE/TM polarised light can well account for this anisotropy and its dependence on pump current.
