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.

Claim (Index 5):
The planar lightwave circuit of  claim 1  wherein the first optical waveguide arm comprises 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, wherein the outer curved heated section and inner curved heated section are adjacent each other with the inner curved heated section having a smaller average radius of curvature than the outer curved heated section and a larger average radius of curvature than the loopback waveguide section such that an open accessible space is formed enclosed in part by the arc of the inner curved heated section.
