Paper Abstract

A distributed feedback (DFB) semiconductor laser with multiple phase shifts based on reconstruction equivalent chirp (REC) technology is numerical studied and fabricated. The simulation results show that the performances of the multiple phase shifts DFB semiconductor laser based on REC technology are nearly the same as the actual multiple phase shifts DFB laser. They have the same P-I curves, the internal power distributions and the output ASE spectra. However, it only changes the sampling structures of the REC based laser with the uniform seeding waveguide grating. So the fabrication of such laser is very easy. In this paper, the fabrication of this structure was realized for the first time to the best of our knowledge. The experimental results show that it has good single longitudinal mode operation even under high injection current with side mode suppression ratio (SMSR) above 55dB even at high injection current.
