    Abstract

    In order to construct an optical triode model, a PT (parity-time) symmetric coupled microcavity with the semiconductor magnetic material InSb is designed. By optimizing structure parameters, the pole effect of PT symmetric structure with strong magnetic coupling is achieved. By changing the input current signal into the change of the applied magnetic field to magnetic materials near the pole frequency, the input current signal at the pole state can be amplified. The amplification can be either in phase or out phase. As a result, a special optical triode model is realized.
