T. Ohtoshi et al., ORIENTATION DEPENDENCE OF OPTICAL GAIN IN ZINCBLENDE-GAN STRAINED-QUANTUM-WELL LASERS, IEEE journal of selected topics in quantum electronics, 4(3), 1998, pp. 527-530
Optical gains in zincblende-GaN strained-quantum-well (QW) lasers are
analyzed theoretically for various crystal orientations. Valence subba
nds are calculated based on the 6 x 6 Luttinger-Kohn model. It is foun
d that the gains in zincblende-GaN strained-QW lasers with (110) orien
tation are much higher than those in wurtzite-GaN lasers with (0001) o
rientation.
