基于STIRAP技术的三个波导间能量转移研究

The Energy Transfer Research between Three Waveguides Based on the STIRAP

基于三能级间的布居转移技术——受激拉曼绝热通道技术,在绝热条件下,设计了一种三波导间相互作用的耦合系数,实现了能量从三波导系统的第一个波导全部转移到第三个波导,并且在整个过程中,中间的波导始终没有能量.利用光学仿真软件模拟出了与理论相对应的仿真实验.结果表明:可以通过设计一种反常的波导间耦合系数,从而实现能量在边界波导间的全部转移.

Based on three-level population transfer technology-Stimulated Raman adiabatic passage technique,we realized the all energy transfer from the first waveguide to the third waveguide under the adiabatic condition,by means of control coupling coefficient of three waveguides,and that the middle waveguide not have any energy. The energy transfer of three waveguides were simulated using Beam PROP. It is identical for the theory and simulated result. The results prove that the energy transfer between the boundary waveguides can be realized by means of design a anomaly coupling coefficient.
