在非线性波导阵列中，可以通过激发一个反常波来实现输入光束的巨大压缩。输入场几乎均匀分布在数百个波导上，几乎将所有能量集中到结构输出平面的单个波导中。我们确定所需的电场输入轮廓来实现这一点。我们通过离散非线性薛定谔方程的直接数值模拟来说明这种现象。
In an array of nonlinear waveguides, a giant compression of the input beam can be achieved by exciting a rogue wave. Input field almost homogeneously distributed over hundreds of waveguides concentrates practically all the energy into a single waveguide at the output plane of the structure. We determine the required input profile of the electric field to achieve this. We illustrate the phenomenon by modeling the array by direct numerical simulations of the discrete nonlinear Schrödinger equation.
