Abstract
The first observation of nonlinear reflection from a Bragg reflector composed of Ga0.8 Al0.2As/AlAs layers due to the band filling effect was measured by the pump probe method. The nonlinearity was primarily due to saturable absorption. Optically induced reflectivity changes of as much as 38% were measured.Keywords
