| 摘 要： | 通过数值模拟方法研究了非线性光子晶体波导中光孤子的传输特性,研究重点是光在基于二维光子晶体材料制作的弯曲波导中的透射行为,结果表明光孤子经过传统方法制作的弯曲波导后能量完全衰减,而通过调制波导弯曲处晶体的结构,光孤子可以完美的传输,没有畸变和能量损耗。此外,也总结了调制波导弯曲处光子晶体结构以提高光孤子的透射率应遵循的原则。

| Abstract: | The propagation of optical solitons through nonlinear photonic crystal （ PC ） waveguids is in- vestigated by finite - difference time - domain （FDTD） method. The studies focus on the waveguide bends in two- dimensional PC. It is found that optical solitons are completely destroyed after passing through the conventional waveguide bend. With appropriate changing the bend structure, however, perfect transmission of optical solitons can be realized. The criteria for the design of waveguide bends with high transmission are analyzed as well. |
