                讲座摘要

                Optical microresonators can confine light within a small dielectric volume for more than 1 microsecond, which result in strong light-matter interaction and extremely fine optical resonance. Since early 1990s, researchers have been using optical microresonators for laser frequency stabilization, ultralow-noise sensing and optical nonlinear conversion. In recently years, frequency comb generation based on optical microresonators have become one of the most fertile fields in applied physics.

                The talk given by Dr. Wenle Weng will cover the fundamental physics of optical microresonators and several applications in laser frequency stabilization, ultra-sensitive thermometry and refractive index sensing. It will also introduce the formation of cavity solitons and soliton interactions in microresonators. Last but not the least, the talk will showcase several recent breakthroughs in low-noise microwave synthesis, optical clock and light detection and ranging based on microresonator frequency combs.
