Whispering gallery mode (WGM) microcavities have a small mode volume, a high quality (Q)
factor and great application potential in the field of integrated optics. The coupling of light …

Optical whispering gallery modes (WGMs) derive their name from a famous acoustic
phenomenon of guiding a wave by a curved boundary observed nearly a century ago. 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 …

Confinement of light into small volumes has become an essential requirement for photonic
