Abstract

We present a novel dual-bottle microresonator with a high ${ Q}$-factor exceeding ${{10}^7}$. Such a resonator consists of two lateral resonators and one central resonator. The maximum diameter of the lateral resonator is $\sim{180}\;{\unicode{x00B5}{\rm m}}$, and the central diameter is 124.91 µm. Characteristics of the whispering gallery mode spectra are investigated and explained by the microbottle resonance, mode interference, and scattering effects. Strain-tuning sensitivity varies from 0.126 to 1.7 pm/µ$\unicode{x03B5}$ when a tapered fiber is placed at the resonator’s different positions. With a coupled area at the middle of the central resonator, the highest, to the best of our knowledge, strain sensitivity of 1.7 pm/µ$\unicode{x03B5}$, which is higher than previously reported solid microresonator strain sensors, is achieved.
