摘要:
Confinement and manipulation of photons using microcavities have triggered intense research interest in both fundamental and applied photonics for more than one decade. Prominent examples are ultrahigh-Q whispering gallery microcavities which confine photons by means of continuous total internal reflection along a curved and smooth surface. The long photon lifetime, strong field confinement, and in-plane emission characteristics make them promising candidates for enhancing light-matter interactions on a chip. In the first part of this talk, I will introduce some representative photonics applications of ultrahigh-Q microcavities, such as ultralow-threshold microlasing (microcomb), cavity quantum electrodynamics, cavity optomechanics, and highly sensitive optical sensing. In the second part, I will focus on the single-nanoparticle detection by using whispering gallery microcavities, which is highly desirable for applications in various fields, such as in early-stage diagnosis of human diseases and in environmental monitoring.
