A 1.55-..mu..m wavelength InGaAsP distributed feedback (DFB) laser with an antireflection coated facet has been coupled to a single-mode fiber with a reflective end to construct a compact narrow-linewidth source. The linewidth of the DFB laser is reduced by a factor of 1000 to 70 kHz at 1 mW output with a 5.5-cm fiber length. The fiber mirror to DFB laser coupling parameters required for narrow-linewidth operation are presented.
