Stress Optic Tuners for Waveguide-Based Devices

Abstract

Disclosed herein is a stress optical modulator. The modulator include a circular piezo-electric actuator; and a ring waveguide separated from the circular piezo-electric actuator by a top cladding layer. The circular piezo-electric actuator may be offset from the ring waveguide such that a first circular portion of the circular piezo-electric actuator is located on the outside of the ring waveguide and a second circular portion of the circular piezo-electric actuator is located on the inside of the ring waveguide. The circular piezo-electric actuator may be configured to change the guiding properties of the ring waveguide based on the voltage applied to the circular piezo-electric actuator by inducing strain through the top cladding layer to change the optical properties of the ring waveguide.
