Enhanced soliton-effect pulse compression by cross-phase modulation in optical ibers

摘要

a new method is proposed to enhance the soliton-effect compressionof optial pulses. It consists of copropagating two optical pulseswith close wavelengths in the anomalous group-velocity dispersionregime of single-mode fibers. Numerical simulations show that, ascompared with the tradi- tional single pulse compression method,cross-phase modulation can not only dramatically increase thecompression ratio but also decrease the optimum fiber length. Theeffects of initial pulse-width mis- match, raman self-scattering, andpulse walk-off on the pulse compression are also discussed.
