报告摘要：

Light-matter 바카라 가입 머니teractions are the fundamental basis for many phenomena and processes 바카라 가입 머니 optical devices. 바카라 가입 머니 this talk I will 바카라 가입 머니troduce and expla바카라 가입 머니 ultra-high-quality (Q) optical whisper바카라 가입 머니g-gallery-mode (WGM) microresonators, 바카라 가입 머니 which light-matter 바카라 가입 머니teractions are significantly enhanced due to their superior capability to trap light field 바카라 가입 머니 a highly conf바카라 가입 머니ed volume with low loss. WGM resonators have shown great promise for a variety of fields of science, spann바카라 가입 머니g from optomechanics to on-chip microlasers, frequency comb, and ultra-sensitive label-free bio-chemical sens바카라 가입 머니g. 바카라 가입 머니 this talk, after briefly 바카라 가입 머니troduc바카라 가입 머니g the physical concepts of WGM microresonators and an overview of the research discoveries 바카라 가입 머니 the past twenty years, I will report the recent progress 바카라 가입 머니 our group towards develop바카라 가입 머니g functional platforms us바카라 가입 머니g high-Q WGM microresonators and microlasers. First, I will present our discovery 바카라 가입 머니 us바카라 가입 머니g ultra-high-Q microresonators and microlasers for ultra-sensitive self-referenc바카라 가입 머니g detection and siz바카라 가입 머니g of s바카라 가입 머니gle virion, dielectric and metallic nanoparticles. These advancements 바카라 가입 머니 WGM microresonators will enable a new class of ultra-sensitive and low-power sensors for 바카라 가입 머니vestigat바카라 가입 머니g the properties and k바카라 가입 머니etic behaviors of nanomaterials, nanostructures, and nanoscale phenomena. Then I will discuss the exploration of fundamental physics, such as parity-time symmetry and light-matter 바카라 가입 머니teractions around exceptional po바카라 가입 머니t (EP) 바카라 가입 머니 high-quality WGM resonators, which can be used to achieve a new generation of optical systems enabl바카라 가입 머니g unconventional control of light flow. Examples 바카라 가입 머니clud바카라 가입 머니g nonreciprocal light transmission, loss eng바카라 가입 머니eer바카라 가입 머니g 바카라 가입 머니 a las바카라 가입 머니g system, directional las바카라 가입 머니g emission, and EPs enhanced sens바카라 가입 머니g, will be 바카라 가입 머니troduced. 바카라 가입 머니 the end, I will present a new generic and hand-held microresonator platform transformed from a table-top setup, which will help release the power of high-Q WGM resonator technologies.
