Abstract
A Mach-Zehnder interferometer has electrodes configured to act as a microe transmission line. The optical waveguide arms have a reflective coating on their distal ends so that light is reflected back through the arms. The microwave transmission line is open-ended in a vicinity of the reflective coating so that microwave energy is reflected at the open end. Thus, the interferometer supports a traveling wave in a reflective configuration, and the distance over which interaction takes place can be effectively doubled.
