Abstract:
An optomechanical radiant energy detector comprising:a substrate; a radiant energy absorber; an anchor mechanically coupled to the substrate; an isolation arm mechanically coupled to the anchor and the radiant energy absorber; a first waveguide having a first waveguide evanescent field, mechanically coupled to the substrate; a second waveguide having a second waveguide evanescent field, said second waveguide being positioned in proximity to the first waveguide, and an actuator mechanically coupled to the second waveguide, the radiant energy absorber and the isolation arm, wherein the actuator is responsive to incident energy on the radiant energy absorber to move the second waveguide to a position at which the first and second waveguide evanescent fields interact.
