Abstract
Space-charge-induced optical nonlinearities for asymmetric coupled qua ntum wells have been studied. Calculations for optimized AlGaAS struct ures show that a blue-shift of the band gap of 9 meV at a carrier dens ity of 10(12) cm-2 can be obtained. Experimental comparisons with a re ctangular well show a large increase in room-temperature nonlinearitie s.
