## Abstract Narrow‐linewidth and wavelength‐tunable operation of erbium‐doped fiber laser (EDFL) by optically feedback‐injecting an intracavity Fabry–Perot laser‐diode (FPLD) driven at nearly threshold condition is demonstrated. An optimized lasing linewidth and a side‐mode suppressing ratio of 0.1
