【 摘 要 】

The absorption coefficients of intersubband optical transitions in the valence band of the AlSb/InAs0.84Sb0.16/AlSb quantum wells in framework of the four-band Kane model. It is established that the light absorption by holes may lead to the laser generation breakdown. It is shown that we need to decrease the quantum well width to range a
