Abstract
An electro-optic switch implemented on a substrate which includes first and second input waveguides of unequal width and a central region in which light from the two input waveguides converge. First and second output waveguides are provided which diverge from the central region. Electrodes for generating an electric field are disposed adjacent the central region and output waveguides for switching a beam of light from the first to the second output waveguide in a step-like manner in response to a control voltage.
