提出并实现了一种基于阵列波导的二维类艾里光束产生技术。结果表明，从阵列波导端面输出的具有准艾里振幅和类艾里相位的光束具有二维类艾里方向图。这些光束在传输过程中具有准无衍射、横向加速和自愈的能力。我们还分析了波的传播沿着这种阵列波导使用耦合模理论和光束传播的方法。(C)2013年美国光学学会
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. (C) 2013 Optical Society of America
