| 摘 要： | 为了获得1维独立空间孤子对在加偏压中心对称双光子光折变晶体串联回路中演化的结果,基于中心对称双光子光折变效应的理论,证明在中心对称双光子光折变晶体串联回路中存在1维独立屏蔽空间孤子对,理论研究了独立暗-暗和明-暗孤子对的空间包络、动态演化和稳定性。结果表明,暗孤子通过光电流能影响孤子对中另一孤子,但明孤子不能。

| Abstract: | In order to study the evolution of separate spatial soliton pairs in a biased series centrosymmetric two-photon photorefractive crystal circuit, separate spatial soliton screening pairs solitons were proved to stay in a series circuit of two-photon photorefractive crystals based on the centrosymmetric two-photon photorefractive effect. The spatial envelope, dynamical evolution and stability of separate dark-dark and bright-dark soliton pairs were investigated numerically. The results show that only the dark soliton can affect the other soliton by light-induced current, but the bright soliton cannot. |
