High Performance optical modulator using Ultra Thin Silicon Waveguide in SOI technology

High performance optical structures based on new platform for the design of photonic structures are proposed in this work. The platform is previously proposed and is based on the design of an ultra thin waveguide with narrow lateral thickness with low confined field inside the core waveguide which enables using this waveguide for building high performance photonic based sensors and modulators. An MZI based modulator is reported with extinction ratio of 20.36 dB. These values resulted in high performance photonic structures as compared to the conventional waveguide based structures delimiting some of the constraints when using photonic structures.
