Abstract
Electro-optic (EO) sensing in internal reflection at the critical angle offers a sensitive means of detecting electrical signals which are confined near the surface of an EO medium. Earlier papers1,2 described the interaction using the nonlinear optical formalism as a χ(2) process. However, this interaction can be more naturally understood using the theory of electro-optics. Thus, here we present a new theoretical explanation of the EO effect in internal reflection using EO formalism.
