The results of work on the creation of tunable single-frequency semiconductor laser modules for a wavelength of 1550 nm with an external cavity based on fiber Bragg gratings (FBGs) formed in a single-mode fiber are presented. The methods for discrete and smooth tuning of the radiation wavelength are considered. The presented laser modules are capable of generating dynamically stable single-frequency radiation with a side mode suppression of more than 40 dB, a lasing line width of 100–500 kHz, and an output optical power of more than 35 mW. The wavelength tuning of the radiation spectrum of the laser module was 1.5 nm.
