Abstract

Liquid crystal (LC) clad–glass core highly multimode waveguides, with a column array of interdigitated electrodes arranged on the LC layer remote from the core–cladding interface, have been electrically switched between guiding and nonguiding states. The time for 63 % recovery is 135–250 μs, and 90% recoυery is ~0.8 ms.
