Yj. Wen et al., Generation of 140GHz optical pulses with suppressed amplitude modulation by subharmonic synchronous modelocking of Fabry-Perot semiconductor laser, ELECTR LETT, 37(9), 2001, pp. 581-582
140GHz optical pulses with a pulsewidth of 2.7ps are generated From a stand
ard Fabry-Perot semiconductor laser using subharmonic optical injection. A
new technique based on optical feed forward modulation is also presented to
suppress the amplitude modulation associated with subharmonic injection.
