Abstract :
Based on low-loss fusion splicing of microfibers using a CO_2 laser, we demonstrate free-standing microfiber closed-loop resonators. Loaded Q-factors of 110 500 with a finesse of 15.3 are obtained around 1.5- wavelength in a 2.4-mm-diameter closed-loop resonator suspended in air. The possibility of tuning resonant responses by changing the coupling efficiency is also demonstrated.
