We propose and demonstrate a two-dimensional (2D) Airy-like beam generation technique based on arrayed waveguides. We show that the output beams with quasi-Airy amplitude and cubic-like phase from an arrayed waveguide end have 2D Airy-like patterns. These beams have the ability to remain quasi-nondiffracting, transverse accelerating, and self-healing during propagation. We also analyze wave propagation along this arrayed waveguide using coupled-mode theory and the beam propagation method.
我们提出并演示了一种基于阵列波导的二维类艾里光束生成技术。我们表明，来自阵列波导末端的具有准艾里振幅和类立方相位的输出光束具有二维类艾里图案。这些光束在传播过程中能够保持准无衍射、横向加速和自愈特性。我们还使用耦合模理论和光束传播方法分析了沿该阵列波导的波传播。
