摘要: In this paper, bendloss characteristics of an optical fibre are investigated in detail, and the results show that the resonator with a smaller ring radius, wider free spectrum range (FSR), higher fineness ($f$) and quality-factor ($Q$) can be achieved by using microfibres. Based on the improved fused taper technique, a high-quality microfibre with 5\,$\mu$m radius has been fabricated, and an all-fibre micro-ring resonator with a radius of only 500\,$\mu$m is realized using self-coiling coupling method. The good-resonant characteristic makes the all-fibre device be expected to avoid bendloss and connection loss associated with planar waveguide integration.
