Stable narrow-linewidth (<100 kHz) operation has been demonstrated for a fiber-extended-cavity distributed-feedback (EC DFB) laser emitting at 1.55 ..mu..m wavelength. We describe the observed oscillation frequency tuning characteristics of the laser obtained by controlling the temperature and injection current. The effects of distributed grating reflection and continuous frequency tuning schemes are examined for both the EC DFB laser and for the case of an EC DBR (distributed Bragg reflector) laser.
