Abstract :
Summary form only given. InGaAs/GaAs strained-layer quantum well structures grown on non-(001) oriented substrates are of fundamental interest for a variety of nonlinear optical elements. We have studied the low-temperature photoluminescence of InGaAs/GaAs (111)B single quantum well structures with 25% Indium mole fraction. The combination of band-gap narrowing and screening of the internal fields leads to complex-carrier-induced nonlinearities in this piezoelectric system.
