Terahertz high-speed on-chip modulator based on SRR

In this paper, we proposed a Terahertz high-speed on-chip modulator based on Split-Ring Resonator(SRR) by combining meta-unit, GaAs Schottky diodes and SRR. This method enhances the resonance intensity by SRR to realize higher modulation depth. The simulation results show that the maximum switching ratio of 33 dB is achieved with the insertion loss of 3 dB. In addition, the on-chip modulator based on SRR proposed in this paper provides an important development direction and concept for on-chip, integrated, high-performance terahertz dynamic devices.
