Abstract

A graphene-assisted microwave photonics filter based on micro-ring resonators is proposed. This setup demonstrated a filter with a flat transmission band and significantly enhanced tunability that a more than 70 GHz frequency shift of the center frequency has realized. The filter will be able to switch by electrical gating on different modes including lowpass, bandpass, and highpass. In the simulation results, the proposed filter exhibits the advantages of high sideband suppression, outstanding rectangular coefficient, and high tunability. Moreover, the construction of filters based on the SOI platform adapts to the developmental requirement of monolithic integration in microwave photonic devices.
