The commercial success of radio-frequency acoustic filters in wireless communication
systems has launched aluminum nitride (AlN) as one of the most widely used …

High-and ultrahigh-Q whispering-gallery mode resonators have the capability to trap
photons by total internal reflection for a duration ranging from nanoseconds to milliseconds …

Chirality is an asymmetric property widely found in nature. Here, we propose and
demonstrate experimentally the spontaneous emergence of chirality in an on-chip ultrahigh …

We report enhanced optical nonlinear effects at the surface of an ultrahigh-Q silica
microcavity functionalized by a thin layer of organic molecules. The maximal conversion …

Optical microresonators are ideal tools for the reduction of the threshold of optical parametric
oscillation based on four-wave mixing. Usually, the efficiency and bandwidth of the resonant …

Whispering-gallery-mode (WGM) microcavities are very important in both fundamental
science and practical applications, among which on-chip second-order nonlinear …

Universal nonlinear scattering processes such as Brillouin, Raman, and Kerr effects are
fundamental light-matter interactions of particular theoretical and experimental importance …

Ultrafast all-optical modulation and efficient frequency conversion are highly required for a
wide range of applications including optical communication, microwave photonics, and …

We report the experimental observation and theoretical analysis of thermo-optic effects in
high-Q on-chip lithium-niobate (LN) microdisks. We find that the resonance transmission dip …

We review the works performed on whispering gallery mode (WGM) micro-optical resonators
made in rare-earth (RE) doped glasses for implementing low threshold and narrow line …
