Abstract

We proposed a 2×2 SOI thermo-optic switch based on microring assisted Mach-Zehnder interferometer(RAMZI) and graphene heater. The thermo-optic switch consists of 2×2 MMI-based 3-dB coupler, and RAMZI with graphene film as heater fixed above the microring resonator. A design and optimization of the switch, including optical characteristics of MMI coupler and MZI, electro-thermal characteristics of graphene heater and the overall performance of the switch, is carried out. The thermo-optic switch is demonstrated with small footprint of 0.07 mm2 , and low power consumption on simulation.
