High performance silicon Mach-Zehnder interferometer based photonic modulator

A new design for silicon Mach-Zehnder photonic interferometer with a different cross-sectional area than that for conventional silicon waveguide is proposed. The structure has the potential to be used as a modulator with extremely large extinction ratio as compared to conventional silicon waveguides based MZI modulators. This enabled using our design in different micro-scale applications including optical sensing and modulation using photonic structures.
