Abstract
An efficient tunable erbium-doped fiber (EDF) ring laser utilizing a single fiber Bragg grating (FBG) and an optical circulator is investigated. The laser demonstrates a threshold of 3.43 mW and a slope efficiency of 12.5%. Tunability of the fiber laser is obtained by thermal tuning of the FBG. Simultaneous temperature tuning demonstrates a 0.01 nm/oC variation in laser wavelength. Key Words: Fiber Bragg grating, fiber laser, tunable laser, ring laser, thermal tuning
