The optical device includes a waveguide and a light sensor on a base. The light sensor includes a light-absorbing medium configured to receive a light signal from the waveguide. The light sensor also includes field sources for generating an electrical field in the light-absorbing medium. The field sources are configured so the electrical field is substantially parallel to the base.
