The design of a cw single-frequency semiconductor laser with a Bragg fibre grating in a composite resonator emitting at a wavelength of 1553.6 nm and intended for fibre-optic communication systems with wavelength-division multiplexing is descried and its main parameters are presented. It is shown that the suppression of longitudinal eigenmodes of the laser diode caused by the antireflection coating deposited on the internal face of the crystal leads to lasing on a single longitudinal mode of the composite resonator. The lasing line half-width is no more than 0.1 nm and the lasing wavelength, which corresponds to the Bragg wavelength of a fibre grating, remains stable in the dynamic mode. (lasers, active media)
