Brief
The article proposes and demonstrates a tunable narrow-linewidth erbium-doped fiber ring laser that utilizes tunable fiber Bragg gratings (TFBGs), achieving a wide tunable range and stable output.
Summary
This paper presents a tunable erbium-doped fiber ring laser that uses a tunable fiber Bragg grating (TFBG) to achieve a narrow linewidth (less than 0.01 nm) and a tunable range of 8 nm in the C band. The TFBG is based on applying strain to a uniform FBG, allowing for wavelength control. The laser also features a side-mode suppression ratio better than 50 dB. Furthermore, the integration of an array waveguide grating (AWG) enables wavelength preselection, and the laser's performance was successfully tested over a 50-km transmission at 10 Gb/s, demonstrating its potential for optical communication applications.
