Abstract
A fibre ring resonator constructed by a strand of single-mode fibre and a mechanically lapped directional coupler is demonstrated. The finesse of the resonator was measured to be as high as 1260. Methods to improve the coupler characteristics are discussed. The device can be used as a highresolution optical spectrum analyser.Keywords
