STRUCTURES AND METHODS FOR PHASE SHIFTING IN OPTICAL DEVICES

Original Abstract Submitted

within integrated photonic circuits the ability to induce an optical phase shift allows multiple circuit elements to be implemented including, for example, modulators and optical switches. it is beneficial to achieve lower power consumption for these phase shift elements to reduce overall power consumption of the photonic circuits and their associated drive circuits. exploiting processing techniques for microelectromechanical systems (mems) designs are outlined for high efficiency thermo-optic phase shifter elements with suspended elements that improve thermal isolation and counteract stress induced phase shifts that reduce the thermal induced phase shift. mems based spring structures provide both mechanical support and thermal pathways for improved responsivity. other designs employ direct mems based modification of the waveguide path length without exploiting thermal based index changes.
