摘　　要：光子集成回路和光子芯片具有低功耗、高速率、大带宽等优势,是下一代光信息处理系统的必然趋势,而片上光源是其中的关键技术。设计了一种基于光学微环谐振腔的光学泵浦激光器,泵浦光与激光通过全光控制输出到不同的波导上。结合四能级-二电子能级模型和时域有限差分法进行电磁场仿真,分析了激光输出和粒子态密度的时域特性及稳态电磁场模式分布,约94 ps后达到稳态粒子数密度反转布居,1064 nm泵浦光和1550 nm激光分别通过上话路的Through端口和下话路的Add端口输出。Photonic integrated circuits(PIC)and photonic chips have the advantages of low power consumption,high speed,and large bandwidth,and they are the inevitable trend of the next generation optical information processing system.And on-chip light source is the key technology of PIC.An optical-pumping laser based on optical microring resonator is proposed,and the pumping light and laser light are output to different waveguides through the all-optical control.Combining the four-level two-electron energy level model and the time-domain finite difference method electromagnetic field simulation,the time-domain characteristics of laser output,particle state density and steady-state electromagnetic field mode distributions are analyzed.After 94 ps,the steady-state particle number density inversion distribution is reached,and pumping light of 1064 nm and laser light of 1550 nm are output to Through port of the upper channel and the Add port of the lower channel,respectively.
