The whispering-gallery mode microdisk or microsphere resonators have supercompact size,
high energy storage, very narrow resonance bandwidth, and high sensitivity. These …

We package a high-quality (Q) factor optical whispering gallery mode (WGM) microsphere
resonator side coupled to two tapered fibers without changing the initial coupling conditions …

A novel in-fiber whispering-gallery mode (WGM) microsphere resonator-based integrated
device is reported. It is fabricated by placing a silica microsphere into an embedded dual …

We show that whispering-gallery modes (WGMs) in optical microresonators can be excited
and detected using a fused-tapered fiber tip (FTFT). The fabrication of FTFTs is simple and …

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