Double refraction and reflection of sequential crystal interfaces with arbitrary orientation of the optic axis and application to optimum design

Abstract

The general formulation of double refraction or internal double reflection for any directions of incidence and arbitrary orientation of the optic axis in a uniaxial crystal is analysed in terms of Huygens’ principle. Then double refraction and double reflection along the sequential interfaces in a crystal are discussed. On this basis, if the parameters of the interface are chosen appropriately, the range of angular separation between the ordinary ray and extraordinary ray can be much greater. It is useful for crystal element design. Finally, as an example, an optimum design of the output end interface for a 2 × 2 electro-optic switch is given.
