As a novel application of silicon-based integrated optics, results from a proposed compact Mach–Zehnder interferometer are presented. The deposition of a ZnO thin-film transducer upon the reference arm of the interferometer transforms this optically passive device into a device with active sinusoidal phase modulation.
