Abstract
A semiconductor optical amplifier having various ratios of TE/TM polarization in a multiple quantum well structure on a substrate formed by growing a certain number of quantum wells under compressive strain and others under tensile strain, as well as buffers. The gain coefficients of the respective well layers are chosen such that the overall TE and TM gains are matched over the whole spontaneous emission spectrum so that the semiconductor optical amplifier is polarization-independent.
