Microresonators are resonators that confine light in micrometer scale mode volume. Microresoantors have become one of the most important elements in nanophotonics and integrated optics technology, including filters, sensors, lasers, optical switches, etc. Geometries as well as material platforms of microresonators are surprisingly diverse, ranging from micro-posts/disks/spheres/toroids/rings, Fabry-Perot and photonic crystal cavities to microcavities on regular/irregular polygonal nanocrystals or even topologically curved surface, and materials from silica, silicon, silicon nitride, lithium niobite, diamond, AlN, crystalline materials including CaF₂ and MgF₂, to III-V semiconductor materials such as AlGaAs. Extreme light confinement by light circulations can significantly enhance light-matter interaction and leads to interesting yet useful phenomena such as dissipative Kerr soliton combs, harmonic generations etc. Combined with new physics from non-Hermitian systems and other disciplines, enhancement performances at optical/phonon lasing, sensing, exotic light propagation have been demonstrated. In order to promote research on the fundamental physics of microresonators and related applications for photonics and beyond, Prof. Heng Zhou (University of Electronic Science and Technology of China, China) and Prof. Jing Xu (Huazhong University of Science and Technology, China) are planning to organize a special issue on Microresonators for photonic applications and beyond. Submission deadline is 15 December, 2022.
