Claim:
1. A circuit device comprising: an array of waveguides in a substrate coupled to a splitter that splits source light into the array of waveguides; an insulating layer on the substrate, the insulating layer having an opening to expose a portion of a path of the array of waveguides; a liquid crystal layer on the insulating layer and on the portion of the path of the array of waveguides exposed by the opening in the insulating layer, wherein a voltage across the liquid crystal layer is to cause a greater phase shift in a given waveguide relative to another waveguide in the array of waveguides exposed by the opening in the insulating layer; and a coupler integrated in the substrate to receive light from the array of waveguides and couple the light through the liquid crystal layer.
