We predict a strong effective Kerr nonlinearity in hollow-core photonic crystal fibers filled with a Raman active gas which exceeds the intrinsic Kerr nonlinearity by 2 orders of magnitude. Two-color bright-bright and dark-bright solitons supported by this nonlinearity are found and the feasibility of their experimental observation is demonstrated.
我们预测，在填充有拉曼活性气体的空心光子晶体光纤中会出现很强的有效克尔非线性，其比本征克尔非线性高出两个数量级。我们发现了由这种非线性支持的双色亮-亮孤子和暗-亮孤子，并证明了对它们进行实验观测的可行性。
