In modern microwave and optical communication systems, it is urgent to develop optical components with the same performance as electronic components. In this paper, a PT-symmetric structure including electro-optical medium is designed to construct optical triode. It is found that the structure has a pole effect of amplification under certain parameters. The frequency of the incident wave at the pole is taken as the carrier frequency, and the electrical signal is modulated into an optical signal. By setting the bias electric field, the modulated optical signal can be amplified in phase and out phase, and even by doubling frequency, and a new optical triode model is obtained. The designed model will play an important role in the design of optical integrated devices.

电光调制下基于PT对称结构的光三极管仿真

在现代微波和光通信系统中，迫切需要开发与电子元件性能相同的光学元件。本文设计了一种包含电光介质的 PT 对称结构来构建光学三极管。发现该结构在一定参数下具有放大的极点效应。以极点处的入射波频率为载波频率，将电信号调制成光信号。通过设置偏置电场，可以对调制后的光信号进行同相和异相放大，甚至倍频，得到一种新的光三极管模型。所设计的模型将在光集成器件的设计中发挥重要作用。
