光折变晶体中低振幅屏蔽孤子的温度特性

Temperature Dependence of the Low-amplitude Screening Spatial Solitons in Photorefractive Crystal

本文在忽略扩散效应的条件下 ,理论研究了加偏压非光伏光折变晶体中低振幅屏蔽孤子的温度特性。结果表明 ,当温度一定时 ,晶体中可形成稳态屏蔽明孤子或暗孤子。通过适当调节温度 ,可以控制孤子的空间形态。

Neglecting the diffusion effect, the temperature dependence of the low-amplitude Screening bright and dark solitions in biased non-photovoltaic photrefractive crystal was discussed. For a stable bright and dark screeing originally formed in a crystal at given temperature. The spatial shape of a stable screening solition can be reshaped by adjusting the crystal temperature.
