Evolution of a stokes wave pumped by an elementary soliton propagating in optical fibers

Abstract

AbstractThe production of a Stokes wave due to a Raman effect pumped by an elementary soliton propagating in optical fibers is studied analytically and numerically. The approximated analytical results show that cross‐phase modulation results in the added periodical amplification of the Stokes wave, and the maximum amplification distance exists due to the soliton pump fiber loss. The numerical results show that the smaller the pulse walk off, the greater the effect of the energy transfer from the soliton to the Stokes wave. © 1993 John Wiley & sons, Inc.
