Demonstration of transverse-magnetic dominant gain in quantum dot semiconductor optical amplifiers
Nami Yasuoka, Kenichi Kawaguchi, Hiroji Ebe, Tomoyuki Akiyama, Mitsuru Ekawa et al.
We demonstrated transverse-magnetic (TM)-mode dominated gain at the 1.5 [mu]m wavelength in semiconductor optical amplifiers (SOAs) with columnar quantum dots (QDs). We show that we can control the polarization dependence of optical gain in QD-SOAs by changing the height and tensile-strained barrie ... [Appl. Phys. Lett. 92, 101108 (2008)] published Tue Mar 11, 2008.
