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 nm and >27 dB are obtained, respectively. Linear wavelength tuning of >4 nm by adjusting temperature of FPLD from 20 to 45 °C is reported. © 2002 Wiley Periodicals, Inc.
