Abstract: A technology of arrays of distributed-feedback semiconductor lasers for the spectral region of 1.55 μm and their characteristics are presented. Stable single-frequency lasing with a side mode suppression ratio higher than 25 dB is demonstrated. The possibility of continuous wavelength tuning in a range of up to 7 nm is shown.

Keywords: distributed feedback, single-frequency lasing, side-mode suppression ratio, semiconductor laser.
