Abstract:
In this talk, I will explore two exciting areas of research involving optical cavities: chiral lasers and micro-resonator strong coupling. I will discuss the challenge of achieving circularly polarized (CP) lasers in organic chiral materials due to the lack of intrinsic mirror symmetry in cavity mirrors, and how overcoming this limitation opens new possibilities for organic chiral laser systems. Additionally, I will introduce the phenomenon of strong coupling in micro-resonators, which occurs when the cavity length reduces to the quantum regime, and share our recent progress in observing Rabi splitting with quasi-2D perovskite materials. These studies highlight the exciting science and potential applications of optical cavities in advancing photonics and quantum technologies.
