We have developed a coupled-mode theory to describe light propagation in triple-core photonic crystal fibers (PCFs) in the nonlinear regime. The propagation equations including nonlinearities have been solved analytically. The nonlinear coupling for symmetric and asymmetric fibers is modeled for different coupling and nonlinear parameters. We investigate nonlinear inter-core coupling experimentally with a single high intensity pump beam. Optical switching of a signal beam in the presence of a control pump beam at a different wavelength is also demonstrated. The self-phase modulation (SPM) parameter gamma in the triple-core PCF studied is determined.
我们已经开发了一种耦合模理论，用于描述非线性状态下三芯光子晶体光纤（PCF）中的光传播。包含非线性的传播方程已得到解析求解。针对不同的耦合和非线性参数，对对称和非对称光纤的非线性耦合进行了建模。我们使用单束高强度泵浦光束对非线性芯间耦合进行了实验研究。还展示了在不同波长的控制泵浦光束存在下信号光束的光开关现象。确定了所研究的三芯光子晶体光纤中的自相位调制（SPM）参数γ。
