Electric quadrupole transition enhanced tthree-wave difference-frequency generation in isotropic medium is investigated. Taking account of the contribution of electric quadrupole interaction, we derive the second-order nonlinear susceptibility. We also discuss the possibility of observation of collision induced second-order nonlinear optical processes. The experiments are performed with 3s→4d electric quadrupole transition in sodium vapor. The experimental results agree...

In this paper, it is demonstrated theoretically that, under the strong dispersion condition, the optical waveguides made of the media with non-central symmetry where the second order nonlinear susceptibility (SONS) is not zero, e.g.the thin-film waveguides and crystalline fibers, can also support these solitons but the nonlinear-index coefficient (NIC) in the nonlinea schro-dinger equation should be substituted by the effective NIC defined here. The results obtained here can be easily extended to...

In this paper, it is demonstrated theoretically that, under the strong dispersion condition, the optical waveguides made of the media with non-central symmetry where the second order nonlinear susceptibility (SONS) is not zero, e.g.the thin-film waveguides and crystalline fibers, can also support these solitons but the nonlinear-index coefficient (NIC) in the nonlinea schro-dinger equation should be substituted by the effective NIC defined here. The results obtained here can be easily extended to discuss the other nonlinear effects connected with the NIC in the media with noncentral symmetry because of the definition of the effective NIC.

众所周知,由非线性Schrdinger方程描述的光学孤子可以在光纤(由中心对称介质构成的光波导)中稳定传输。本文在理论上证明,在强色散的条件下,非中心对称介质构成的光波导中(比如薄膜波导,晶体光纤等),同样可传输这种光学孤子。由于定义了等效折射率系数,本文的结果还可用来讨论此类波导中与非线性折射率相关的其他非线性光学效应,比如自相位调制效应等。
