Results show that the parallel transmission intensity approximately shows an exponentially decline distribution while the vertical one displays a rising - then - declining trend 利用實驗數(shù)據(jù),分析了垂直、平行方向上透射光強的變化趨勢,得出平行偏振分量透射光強大致呈指數(shù)下降的趨勢,垂直偏振分量透射光強先略微上升而后下降。
Under certain conditions , in spite of their different modal indices the two polarized components of the pulse can trap one anther and move at a common group velocity due to xpm , the phenomenon referred as self - trapping occur 在一定條件下,盡管脈沖的兩個偏振分量的模式折射率不同,但由于交叉相位調(diào)制效應(yīng),它們能相互俘獲并以共同的群速度傳輸,產(chǎn)生自捕獲現(xiàn)象。
