奇偶对称波导中的基态光学模式及其稳定性

Ground Optical Mode and Stability in PT-symmetry Waveguide with Scarff II Potential

考虑一个特殊的非线性奇偶对称模型,研究相关的基态光学模式,并通过功率和复折射率虚部的振幅之间的依赖关系来直观地判断光学模式的稳定性,这对理解和掌握奇偶对称复折射率分布波导中的光传输特性具有非常重要的实际意义。

Ground optical mode and stability in PT-symmetry waveguide with Scarrff II potential are considered in this paper. The stability of the ground mode can be estimated intuitively according to the independent relationship between the total power and the imaginary amplitude. This is meaningful for us to comprehend and grasp the propagation properties in PT -symmetry waveguide.
