Abstract :
This paper describes the experimental results on two types of electrooptically controllable leaky anisotropic waveguides using nematic liquid crystal (LC) overlayers. In these constructions the conversion of a guiding structure into a leaky one or a reverse operation is feasible by applying an electric field. They showed a switching of millisecond order with an extinction ratio of 20 dB at 30-V peak-to-peak (p-p) applied.
