Abstract

An integrated-optical circuit receives optical signals and modulates and reflects incoming optical signals. The integrated-optical circuit includes a light guide with at least one Bragg resonator evanescently coupled to light guides and a photocell coupled to a Bragg resonator as well as a modulating device that modulates and reflects an additional optical signal that is received.
