Abstract: Mach-Zehnder interferometers comprise heater elements configured to have projections in the plane of optical waveguides positioned such that two adjacent sections of one optical waveguide arms are heated by a common heater element. The heater and at least a substantial section of the heated waveguide segments can be curved. Configurations of an optical waveguide arm can comprise an outer curved heated section, an inner curved heated section, and a loopback waveguide section connecting the outer curved heated section and the inner curved heated section, with average radius of curvature selected to form an open accessible space. Appropriate configurations of the two optical waveguide arms provide for nested configurations of the arms that provide for a compact structure for the interferometer.

Abstract: Energy efficient thermo-optic phase shifters have a configuration with two sections of a waveguide adjacent for heating by a common heater. A loop section can connect the two heated waveguide sections. Further improved efficiency can be achieved in which the heated sections are curved to allow closer placement of the adjacent waveguides. The heater can be curved to follow the configuration of the curved heated waveguide sections. Energy efficiency gains can be up to approximately a factor of two over corresponding traditional thermo-optical phase shifter designs.
