CW injection locking of mode-locked semiconductor lasers has been experimen
tally demonstrated. The phases of the mode-locked frequency comb are shown
to be coherent with that of the master CW laser. The pulsewidth of the mode
-locked laser remains almost unchanged (<2 ps) for a broad range of injecti
on power (-28 to -12 dBm), Pulling of the entire mode-locked frequency comb
by 400 MHz has been demonstrated. The coherent multifrequency source can b
e used as a local oscillator comb for coherent optical channelizers for ult
rawide-band RF signals.
