高斯背景光束上的光怪波产生的研究

Optical rogue waves in a nonlinear graded-index waveguidewith variable coefficients are studied. An exact rogue wave solution on Gaussianbackground beam is presented, in contrast to the previous studies about rogue waves on plane wave background. It is shown that the characteristics of rogue wavesare maintained on Gaussianbackground beam, even that the beam's width is a bit smaller than the rogue waves scale.These results may raise the possibility of relatedexperiments and potential applications in nonlinear optics.
