A Whispering Gallery Mode Microsphere Resonator Integrated With Angle Polished Multimode Fiber

We demonstrate a robust whispering-gallery-mode (WGM) microsphere resonator, fabricated by splicing two sections of multimode fiber (MMF) with end face polished to an angle of 45 degree. The polished end faces are etched by hydrofluoric (HF) acid to form an elliptical-shaped cavity to embed a micros...
