Abstract
To generate ultrashort pulse train at a high repetition rate, Zn was doped to the active region of distributed-feedback lasers. Increase in the differential gain and reduction of the carrier lifetime have been confirmed. The 3 dB bandwidth was increased to 16 GHz. The 14 ps single longitudinal mode optical pulse train at a repetition rate of 14 GHz was generated by gain-switched operation.Keywords
