演讲者简介：
孙一藩目前在比利时布鲁塞尔自由大学担任博士后研究员。他于西安电子科技大学完成本科学习，在电子科技大学获得硕士学位，随后在法国萨克雷大学取得博士学位。他先后于2022年和2024年两次获得欧盟玛丽居里学者资助，分别在意大利罗马智慧大学和布鲁塞尔自由大学开展博士后研究。他的研究方向主要集中在锁模激光器、光纤多模光孤子以及光学腔耗散孤子等非线性光学现象的动力学特性。迄今为止，他在国际学术期刊上发表论文27篇，并在国际学术会议上作报告15次。
讲座摘要：
Temporal cavity solitons in coherently driven passive Kerr cavities have become a focal point in photonics research over the past decade. These solitons are associated with the generation and manipulation of coherent optical frequency combs, which are primarily generated within two platforms: macroscopic fiber rings and microresonators. Soliton formation depends on a delicate balance, involving the interplay of dispersion and nonlinearity, as well as an equilibrium between cavity loss and external driving pump. The dynamics and stability of DS have been extensively studied through a mean-field analysis, wherein the evolution of the electric field in the passive Kerr resonator is described by a driven and damped nonlinear Schrodinger equation, also known as the Lugiato-Lefever equation. In this talk, I will focus on the nonlinear dynamics of ring resonators with an internal phase modulator and multimode solitons from my postdoctoral research, and the soliton generation in a mode-locked nanolaser from my PhD research.
