We propose and demonstrate a approach for Airy-like wave generation using one-dimensional arrayed waveguides instead of a cubic phase plate and a Fourier lens. We show that this Airy-like wave with quasi-Airy amplitude and quasi-cubic phase from arrayed waveguides end has abilities to remain quasi-nondiffracting and freely accelerating during propagation. We also study wave propagation in these waveguides based on supermode theory and beam propagation method. The numerical results are in good agreement with theoretical prediction.
我们提出并演示了一种使用一维阵列波导而不是立方位相板和傅里叶透镜产生类艾里波的方法。我们表明,这种具有类艾里振幅和准立方位相的类艾里波从阵列波导末端发出后,在传播过程中仍具有准无衍射和自由加速的能力。我们还基于超模理论和光束传播法研究了这些波导中的波传播。数值结果与理论预测吻合较好。
