Abstract :
The new all-fiber compound ring resonator has two rings: a primary one that serves as a resonator, and a secondary one that serves as a filter. The main contribution of this resonator is to increase the free spectral range by choosing the fiber lengths in the compound ring cavity. This resonator with a large free spectral range can be readily used as a doped fiber laser. The optimum resonant conditions of the resonator are discussed by using an equivalent model and by the transfer matrix method. The frequency responses of the output and of the circulating intensities are given. Mode suppression by the vernier effect is demonstrated. Comparison with a fiber Fox-Smith resonator is also presented
