Title: Transmission line driven slot waveguide mach-zehnder interferometers

Abstract: A Mach-Zehnder interferometer useful for analog or digital optical signal manipulation. In one example, the MZI is configured as an optical device that provides a balanced output. In another example, the MZI is configured as an optical device that provides a single ended output. Each device uses a silicon split or slotted wave guide having an electro-optically active material present within the slot. The balanced output device uses two slotted wave guides in push-pull configuration.
