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.</p><p><em><strong>Key Words</strong></em>:&nbsp; Fiber Bragg grating, fiber laser, tunable laser, ring laser, thermal tuning</p> ER -
