Abstract
Erbium-doped fiber lasers (EDFL) are attracting a great deal of attention in the optical communications industry. This is due mainly to the fact that the gain spectrums of these lasers are well matched to the output spectrum of erbium doper fiber amplifiers (EDFA) in the 1550 nm operating window. Many different configurations for the fiber lasers have been developed in recent years. The two most popular are ring and linear cavity lasers. Ring lasers can be designed to have a large tuning range when consideration is given to active fiber length and output coupling ratios. Here an erbium-doped fiber ring laser is modeled for comparison of input pump powers and active fiber lengths. Theoretical analysis is given based on values of optical component losses for couplers, isolators, and tuning elements. We will present the laser output powers that are dependent on the output couplers reflectivity for a range of optical pump powers and various active fiber lengths.
