基于损耗引入的高速硅基热光相移器

数据通过实验与仿真得到，利用matlab对采集到的数据进行处理。为了解决金属电极热光相移器速率受限问题，本文通过在系统中引入损耗，使系统处于对称性破缺状态。该状态下，金属热电极可以近距离放置在波导侧面进行加热。由于热电极与波导之间的介质层减少，热相移器的速率得到了显著提升。其响应带宽达到了280kHz，远远超过传统金属电极热光相移器。The data were obtained through experiments and simulations, and the collected data were processed using MATLAB. To address the rate limitation issue of metal-electrode thermo-optic phase shifters, this work introduces loss into the system to place it in a symmetry-broken state. In this state, the metal thermal electrodes can be placed closely adjacent to the side of the waveguide for heating. As the dielectric layer between the thermal electrode and the waveguide is reduced, the response rate of the thermo-optic phase shifter is significantly improved. Its response bandwidth reaches 280 kHz, which is far higher than that of conventional metal-electrode thermo-optic phase shifters.
