Bound states in the continuum (BICs) have emerged as a powerful platform for boosting light–
matter interactions because they provide an alternative way of realizing optical resonances …

We demonstrate an optical underwater acoustic sensor with high sensitivity and broad
bandwidth (10 Hz to 100 kHz), based on the packaged optical microbubble whispering …

An optofluidic DNA biosensor based on a suspended core fiber (SCF) has been proposed
for the detection of specific DNA sequence fragments. The sensor is formed by coupling a …

A micro-ring resonator structure was fabricated via the two-photon polymerization technique
directly on a single-mode fiber tip and tested for refractive index sensing application. The …

Ethanol gas has been widely used in biomedicine, transportation, and chemical industry.
However, when ethanol gas reaches a certain concentration in a closed space, it is possible …

In this paper, a compact fluorescent probe based on fluorescence intensity ratio (FIR)
technique is proposed for real-time thermal monitoring of chips, the sensing unit of which is …

The applicability of whispering gallery mode (WGM) microsphere resonators is limited due to
the intricate modes and dense spectrum they exhibit. This article investigates the spectral …

An erbium-doped whisper gallery mode microlaser is presented, which consists of an
erbium-doped microsphere placed in an optical fiber open microcavity. The erbium-doped …

Optical whispering gallery mode (WGM) microbottle resonators based on a variety of
polymer materials (benzocyclobutene (BCB), UV88 (Relentless, China) and Loctite3525 …

Single‐mode lasing with high‐beam quality and wide‐range spectral purity is of
fundamental importance in scientific and technical applications. Lacking a mode selection …
