Abstract
An optical component is disclosed. The optical component includes a tap waveguide and a primary waveguide positioned on a base. The tap waveguide is configured to receive a portion of a light signal traveling along the primary waveguide. The portion of the light signal received by the tap waveguide is the tapped portion of the light signal. A direction changing region is configured to receive the tapped portion of the light signal from the tap waveguide and to direct the tapped portion of the light signal travels away from the base. A light sensor is configured to receive the tapped portion of the light signal from the direction changing region.
