Abstract : The problem of direct interband transitions in semiconducting crystals is considered in detail. The solution of the problem is shown to lead to a system of simultaneous coupled nonlinear differential equations. These equations do not distinquish between static and dynamic fields, and are obtained without recourse to any approximation procedures. They therefore apply for electromagnetic fields of arbitary amplitude. It is shown, finally, that the linearization of these equations correctly predicts the fundamental optical edge and the photoconductive rate equations which result in photomixing phenomena. (Author)
