We present a comprehensive overview of sensor technology exploiting optical whispering
gallery mode (WGM) resonances. After a short introduction we begin by detailing the …

Optical microcavities with whispering‐gallery modes (WGMs) have large potential and, in
particular, those with a tubular geometry have attracted increasing attention due to their …

Dense photonic integration promises to revolutionize optical computing and
communications. However, efforts towards this goal face unacceptable attenuation of light …

This paper reports a dramatic reduction in plasmon resonance line width of a single Au
nanorod by coupling it to a whispering gallery cavity of a silica microfiber. With fiber diameter …

Laser based on single plasmonic nanoparticle can provide optical frequency radiation far
beyond the diffraction limit and is one of the ultimate goals of nanolasers, yet it remains a …

Metal-dielectric micro/nano-composites have surface plasmon resonances in visible and
near-infrared domains. Excitation of coupled metal-dielectric resonances is also important …

We have developed a robust method for the unprecedentedly accurate angstrom-scale
detection of local variations of the fiber radius based on the idea suggested by Birks et …

An all-optical tunable optofluidic ring resonator (OFRR) is proposed and experimentally
demonstrated. The all-optical control of a silica microresonator is highly attractive, but it is …

Microresonators are ideal systems for probing nonlinear phenomena at low thresholds due
to their small mode volumes and high quality (Q) factors. As such, they have found use both …

A highly sensitive platform is demonstrated for hydrogen gas (H 2) sensing based on a
polymer microcylinder ring resonator (PMRR) obtained by an optical fiber coated with an …
