Ys. Cho et Wy. Choi, Analysis and optimization of polarization-insensitive semiconductor optical amplifiers with delta-strained quantum wells, IEEE J Q EL, 37(4), 2001, pp. 574-579
Polarization sensitivity of semiconductor optical amplifiers (SOAs) with de
lta-strained quantum-well(QW) structures is investigated, The valence band
structures and TE, TM optical gain spectra are calculated for the various d
elta-strained QW structures, It is shown that the number and location of th
e delta layers affect the polarization dependence of the delta-strained qua
ntum well SOA signal gains. The optimal delta-strained QW structure for the
SOA application is identified and its theoretical verification is provided
