What are Whispering Gallery Modes? Whispering gallery modes (WGMs) are a fascinating phenomenon that occurs in both optical and acoustic systems when waves are confined and circulate within a circular ...

Microresonators formed on or within optical fibers confine light in compact volumes, enabling resonant enhancement of optical fields through whispering-gallery modes or axial photonic structures. The ...

Whispering gallery mode (WGM) microresonators confine light by continuous total internal reflection along a curved dielectric boundary, yielding ultrahigh quality factors and small mode volumes. The ...
