Tunable single-frequency source based on a DFB laser array for the spectral region of 1.55 μm

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 ra...

Description
Summary: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.
