我们表明,一个模型的基础上的高群速度失配间隙引导和折射率引导模式之间的反交叉描述光子晶体波导中的间隙孤子传输。这种非线性的解决方案可以用来探索新的制度,如全光控制的群速度(色散慢光)在亚毫米长度尺度,传播超过线性模式截止。通过时域有限差分仿真验证了结果。
We show that a model based on anticrossing between highly group velocity-mismatched gap-guided and index-guided modes describes gap soliton propagation in photonic crystal waveguides. Such nonlinear solutions can be exploited for exploring new regimes such as all-optical control of group velocity (dispersionless slow light) over a submillimeter length scale, and propagation beyond the linear modal cutoff. The results are validated by means of finite-difference time domain simulations.
