Abstract

The nonlinear saturation of the excitonic absorbtion in a GaAs-In_xGa _1-xAs multiple quantum well sample consisting of 80 wells was investigated in the vicinity of the excitonic resonance at 991 nm using a tuneable titanium sapphire laser probe. This characterization yields a saturation intensity s of less than 50 kW/cm and a maximum off-resonance nonlinear refractive index of 6.42 x 10^-7 cm²/W. It is shown that this dispersion can lead to practical optically bistable etalons fabricated from these multiple quantum well structures.
