Abstract :
A new method for generating optical short pulses using tandem connected electroabsorption modulators driven by sinusoidal voltages was proposed. Theoretical estimation shows that pulse trains with 2% duty cycle can be obtained. Pulse trains with 8% duty cycle at 5 GHz repetition rate were experimentally generated.
