Abstract
A transition from a symmetric to an asymmetric waveguide can serve as a mode‐ and polarization‐dependent light‐wave coupler. Coupling experiments with an efficiency up to 70% are reported. Furthermore, total reflection occurs at the transition if the angle of incidence of the guided wave exceeds a critical value. Coupling and total reflection are explained, using the concept of the effective refractive index.This publication has 8 references indexed in Scilit:
