Abstract :
Theoretical analysis of electro-optic tunable filters (EOTFs) using colinear and noncolinear interactions is presented. An effective electro-optic coefficient is derived for various classes of birefringent crystal. We propose to implement the EOTF using the nonlinear photorefractive effect. The photorefractive EOTF can be used for optical storage.
