Abstract
The device includes a main waveguide on a base. The main waveguide is configured to guide a light signal through a light-transmitting medium. The device also includes multiple transition waveguides on the base. Each of the transition waveguide intersects a terminal end of the main waveguide such that each transition waveguide receives a different portion of the light signal from the main waveguide. The device also includes one or more light sensors positioned on the base. Each transition waveguide guides the received light portions to the one or more light sensors such that each of the light signal portions is received at the one or more light sensors.
