ON THE USE OF FIBER-INDUCED SELF-PHASE MODULATION TO REDUCE CHROMATICDISPERSION EFFECTS IN MICROWAVE MILLIMETER-WAVE OPTICAL-SYSTEMS/

In this letter, a novel approach to compensate for the dispersion-indu ced power penalty in externally modulated 1550-nn analog fiber-optic s ystems is presented. The principle is based on the use of fiber-induce d self-phase modulation to generate a chirp distortion effect opposite to that induced by the chromatic dispersion. A significant reduction of chromatic dispersion effects is achieved, which results in augmenti ng the frequency-length product of the fiber-optic link. It is theoret ically and experimentally shown how this dispersion compensation may b e controlled by means of the optical power injected to the optical fib er.
