Abstract

We report spectral feature of a frequency-shifted-feedback semiconductor laser with the anti-reflection coating of low reflectivity on the output facet. Although many peaks due to the chip mode were observed, a few peaks are connected each other without break showing a continuous spectral range wider than 100GHz. A homodyne detection of the laser output showed higher order beat signals supporting the continuity of the laser spectrum over wide spectral range.
