Summary :

A novel method for manipulating chirping characteristics of ultrashort optical pulses is proposed that utilizes cross-phase modulation induced in optical fibers by an intense pump pulse. To examine the effect of cross-phase modulation in optical fibers, blue-shift chirping profiles of CW 1.3 µm light from a distributed-feedback laser-diode (DFB-LD) induced by an intense pump pulse from a 1.3 µm mode-locked YAG laser are observed using time-resolved spectroscopy. The ratio of the two corresponding nonlinear indices (n_{2 XPM}/n_{2 SPM}) is found to be 1.8 from the obtained chirping profiles of the pump and signal, which is in good agreement with the theoretical value of 2. All-optical chirping manipulation of a 40 ps red-shift optical pulse from a gain-switched DFB-LD at 1.3 µm is successfully demonstrated for the first time to our knowledge by compensating for the original signal chirp utilizing cross-phase modulation by a 110 ps intense pump pulse. This method provides a new all-optical approach to controlling the phase or chirping characteristics of optical signals and provides a convenient and flexible way of generating ultrashort pulses with desired chirping characteristics and time durations.
