摘要
为了构建光学三极管模型,设计了一个基于半导体磁性材料InSb的PT(parity-time)对称耦合微腔的结构模型。通过结构参数优化,产生了PT对称结构磁场强耦合的极点效应。在极点频率附近,通过改变输入电流信号改变施加在磁性材料上的磁感应强度,实现极点状态下信号的放大输出。这种放大可以是同相,也可以是反相,该设计实现了特殊光学三极管模型。
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.
