一个模型为分析 multicore 基于繁殖率方程被建立在 18 核心 photonic 水晶纤维(PCF ) 的横向的模式获得分发激光。二种反馈洞被用于纤维激光,它是 buttcontact 镜子和 Talbot 洞。根据模型的意见,在不同反馈洞的横向的模式比赛数字地被模仿。结果证明 Talbot 洞能改进同相的 supermode 获得,当时压制另外的 supermodes。
A model based on propagation rate equations is built up for analyzing the multicore Iransverse mode gain distribution in an 18-core photonic crystal fiber (PCF) laser. The two kinds of feedback cavities are used for the fiber laser, which are the buttcontact mirror and the Talbot cavity. According to the model, the transverse mode competitions in different feedback cavities are simulated numerically. The results show that the Talbot cavity can improve in-phase supermode gain, while sunnress other sunerrnodes.
