摘要

We proposed a method to generate pulsewidth-tunable carrier-suppressed (CS) optical pulsetrain from a mode-locked distributed Bragg reflector (DBR) laser diode (LD) operating with two carrier wavelengths. Our new method made it possible to generate the CS pulsetrains with widely tunable duty ratios of both more and less than 0.5 from a single chip of semiconductor device. With theoretical explanat...
