Abstract

We report the first long-wave infrared (LWIR) nonlinear optical (NLO) investigation of semiconductor superlattices with indirect energy gaps, where the indirectness may be in either real space or momentum space. These bandstructure-engineered materials uniquely combine the properties needed for LWIR limiters, switches and modulators
