Electro-optic Y-junction modulator/switch

Abstract

A new type of electro-optic channel-waveguide modulator/switch for integrated optics has been proposed and demonstrated in which the transverse confinement of The guided optical wave in a channel waveguide is controlled and the optical energy is selectively fed to either Y-junction output port by control of the applied electric field. The device exhibited 75% modulation depth for an applied voltage swing of 6 V peak to peak and a potential bandwidth of 10 GHz.
