| 摘 要： | 自散焦介质中双光束斜入射耦合能发生光束偏转,通过数值模拟发现在非线性折射率不是均匀分布时光束偏转能降低抽运光功率并且偏转角度不减小,在相同的功率条件下,能产生更大的偏转.此现象对光开关的研究有一定的参考价值.

| Abstract: | In this paper,dual-beam transmission problem that possess to a certainty included angle and gains the nonlinear Schrdinger coupled equation(NNLSE) in self-defocusing media is discussed.Our numerical results show that,the probe beam deflexed by the XPM of the pump beam is bigger in self-defocusing medium of nonuniform nonlinear refractive coefficient,and the power of the pump beam is comparative on the small side. |

| Keywords: | nonlinear refractive coefficient cross-phase modulation effect self-defocusing medium focusing of optical beams |
