Optical whispering-gallery mode (WGM) microresonators, confining resonant photons in a
microscale volume for long periods of time, strongly enhance light-matter interactions …

Whispering gallery mode (WGM) resonators have been exploited as a highly sensitive and
efficient sensing technique in the past few years. They offer the advantages of ultrahigh …

Pound–Drever–Hall (PDH) technology is a frequency stabilization technology, which is
widely used in laser frequency stabilization systems. The high-frequency stability in this …

Whispering gallery mode (WGM) resonantors are famous for high-quality factor, low loss,
small size, and low sample requirement. A considerable sensor application has grown up …

A microbubble-probe whispering gallery mode resonator with high displacement resolution
and spatial resolution for displacement sensing is proposed. The resonator consists of an air …

Optical microcavities have the ability to confine photons in small mode volumes for long
periods of time, greatly enhancing light-matter interactions, and have become one of the …

In this work, we show that the application of a sol-gel coating renders a microbubble
whispering gallery resonator into an active device. During the fabrication of the resonator, a …

An ultrathin-film microring laser was fabricated using inkjet printing and a simple lift-off
technique. Whispering-gallery-mode lasing was observed under optically pumped …

We propose an effective method for biomolecular detection based on an external
referencing optofluidic microbubble resonator system (EROMBRS), which possesses good …

Self-assembled microspherical aggregates that work as whispering gallery mode (WGM)
optical resonators are synthesized from a novel hygroscopic polymer covalently appended …
