In this paper, we describe the development (which includes theoretical modeling, structure design, material growth, and sample characterizations) of SiGe superlattices (SL) for nonlinear optical applications in infrared. Our theoretical model predicts that the two-photon absorption coefficient in SiGe (110) SL structures can be on the order of 1 cm/KW, with very fast response (approximately 1 ps). In addition, we also show that quantum well materials with enhanced nonlinear refraction and moderate absorption offer potential advantages for applications in a lowest order Fabry-Perot etalon.
