Abstract

We demonstrate a strain-based near-lossless, fully tunable, whispering gallery mode (WGM) resonator made of an in-fiber rectangular air bubble, which is fabricated by splicing two segments of standard single-mode fibers. With a 39 μm order radius and 1 μm order wall thickness, this type of resonator has a high-quality factor exceeding 10⁶. The tuning of resonant wavelength is realized by applying tensile strain to the resonator, and the voltage-tuning rate of the WGM resonance peaks is about 31.96 pm/V, and the corresponding tuning accuracy is better than 0.03 pm.
