ULTRA-HIGH REPETITION RATE OPTICAL PULSE GENERATION BY CONTINUOUS LIGHT INJECTION INTO A CONTINUOUS-WAVE OPERATED DISTRIBUTED-FEEDBACK LASER

We present a new method to generate short optical pulses with repetiti on rates from 20 to beyond 100 GHz based on the injection technique. N o electrical modulation current is required. The light injection from one continuous wave (CW) operated multi quantum well (MQW)-DFB-laser i nto another generates stable sinusoidal laser pulses. Transmission of the pulses over a dispersion shifted fibre (DSF) generates solitons wi th the desired pulse width and a time bandwidth product of 0.315.
