An optical-fiber Fox-Smith resonator was demonstrated for the first time to our knowledge. It was applied to obtain single-longitudinal-mode operation from an erbium-doped fiber laser. Both the passive performance and the active performance of the device are studied in detail. Good agreement is found between theoretical and experimental results.
