摘要: 为了研究双光子独立屏蔽光伏孤子对的演化和自偏转,对外加电场双光子光伏光折变晶体串联回路中暗-暗和明-暗独立孤子对中的两孤子的动态演化、稳定性和自偏转进行了数值研究。结果表明,在光束的空间展宽远小于晶体宽度的极限条件下,暗孤子通过光电流能影响孤子对中另一孤子的动态演化和稳定性,但明孤子不能影响另一孤子;对于明-暗孤子对,明孤子的偏转程度随暗孤子的入射强度的增加而减小。该结果为工程实现提供了可能。

Abstract: In order to obtain the behavior of evolution and self-deflection of two-photon separate screening-photovoltaic soliton pairs,the dynamical evolution,stability and self-deflecton of both solitons in separate dark-dark and bright-dark soliton pairs in a biased serial two-photon photorefractive crystal circuit were simulated.Under the limit conditions the optical wave has a spatial extent much less than the width of the crystal,only the dark soliton can affect the dynamical evolution and stability of the other soliton with the help of light-induced current,but the bright soliton cannot.For a bright-dark soliton pair,the deflection angle of the bright soliton decreases with the increase of the input intensity of the dark soliton.
