| 摘 要： | 通过数值模拟的方法,研究了单光子、双光子光折变模型中亮屏蔽—光伏孤子特性。结果表明：在同样的外加条件下,双光子光折变模型中亮屏蔽—光伏孤子的半峰全宽小于单光子模型,孤子中心的自偏转距离大于单光子模型。改变外加参量,双光子模型中亮光伏孤子的半峰全宽略小于单光子模型,两模型中孤子中心的自偏转距离几乎相等;单光子光折变模型与双光子光折变模型中亮屏蔽孤子的半峰全宽、自偏转距离等特性相同。

| Abstract: | The characteristics of bright screening-photovoltaic solitons are numerically investigated based on single-photon and two-photon photorefractive model.The resulted obtained indicates that,at the same conditions,the full-width at half maximum（FWHM） of bright screening-photovoltaic solitons in two-photon photorefractive model is smaller than single-photon model and the self-deflection of solitons in two-photon photorefractive model is bigger than single-photon model.After altering the conditions,the FWHM of bright photovoltaic solitons in two-photon model is smaller than single-photon model but the self-deflection of solitons is almost similar in two models.The characteristics of the FWHM and the self-deflection for bright screening solitons are sameness in two photorefractive models. |
