TIME-RESOLVED MEASUREMENT OF DYNAMIC FREQUENCY CHIRP DUE TO ELECTROSTRICTION MECHANISM IN OPTICAL FIBERS

The electrostrictional excitation of acoustic waves by Light pulses in optical fibers results in a timing jitter in soliton transmissions wh ich, in turn, imposes a limitation on the transmission rate in long-di stance communication systems. In this letter, we report for the first time an experimental investigation of this electrostriction effect by time-domain resolution dynamic frequency shift measurement in a coprop agating probe and pulse signal arrangement. The experimental results s how a very good agreement with the theoretical model reported by Diano v.
