Abstract :
A feedforward modulation technique is used to suppress amplitude modulation associated with 40-GHz pulses generated from a subharmonically mode-locked semiconductor laser. It is shown that the amplitude modulation can be suppressed by as much as 20 dB. The improvement of amplitude modulation is shown for different subharmonic numbers.
