Abstract
We report the fabrication and testing of a GaAs electro-optic directional-coupler (EDC) switch in which the fraction of light coupled from one waveguide channel to the other can be controlled by an applied electric field. Ninety-five percent amplitude switching and a maximum extinction ratio of 13 dB have been observed in an EDC switch, having a minimum 3-dB bandwidth of ≳100 MHz and a drive power per unit bandwidth of <180 μW/MHz.Keywords
