Abstract

The fundamental understanding of the nonlinear optical properties of semi-conductors has presented interesting challenges in both theoretical and experimental physics for the past thirty years. However, there have been very few full bandstructure calculations of the nonlinear optical properties of semiconducting materials, be they bulk or superlattice. The primary difficulty is the complexity of the nonlinear response function itself, combined with the requirement of knowing both the electronic energy bands and wavefunctions throughout the Brillouin zone (BZ).
