Abstract :
Polarization sensitivity of semiconductor optical amplifiers (SOAs) with delta-strained quantum-well (QW) structures is investigated. The valence band structures and TE, TM optical gain spectra are calculated for the various delta-strained QW structures. It is shown that the number and location of the delta layers affect the polarization dependence of the delta-strained quantum well SOA signal gains. The optimal delta-strained QW structure for the SOA application is identified and its theoretical verification is provided
