title: Two-dimensional Airy-like beam generation by coupling waveguides.
abstract: 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.
