Abstract
The light sensor is included on an optical device having a waveguide on a base. The waveguide is configured to guide a light signal through a crystalline light-transmitting medium. The light sensor is also positioned on the base and is configured to receive the light signal from the waveguide. The light sensor includes a planar interface between two different materials. The interface is at a 45° angle relative to a <110> direction of the light-transmitting medium.
