In this letter, we demonstrate uncooled and no mode-hop induced signal deterioration, operation of an external cavity diode laser (ECDL) employing a fiber grating. The ECDL achieved 2.5-Gb/s direct modulation and good lasing wavelength stability (< 1 nm) in a temperature range of -5 °C to +45 °C. Our ECDL is suitable for next generation coarse-wavelength-division-multiplexing access network applications.
