Th. Cho et al., THEORETICAL-STUDY ON INTERVALENCE BAND ABSORPTION IN INP-BASED QUANTUM-WELL LASER STRUCTURES, Applied physics letters, 68(16), 1996, pp. 2183-2185
Intervalence band absorptions of 1.5 mu m light in various InGaAs/InGa
AsP quantum well laser structures are investigated theoretically. The
intervalence band absorption formalism based on 6x6 Luttinger-Kohn Ham
iltonian is developed. The absorption tends to decrease with the barri
er height of quantum wells. The tensile strain in the well causes the
absorption to reduce, while the compressive strain causes it to increa
se. Also is found that the absorption decreases with increase in tempe
rature. (C) 1996 American Institute of Physics.
