摘要：
We propose and demonstrate a tunable optical filter based on a tapered silica microcylinder,whose diameter is gradually varied along its longitudinal axis.The tapered microcylinder comprises a slowly varying transition zone fabricated through the fiber drawing technique.Given the tapered diameter of the microcylinder,the resonant wavelengths can be tuned by displacing the tapered microcylinder.This tunable filter exhibits a high Q-factor（10;） and a large tuning range(>1 free spectral range（FSR）).
