Generation of Airy-like wave with one-dimensional waveguide array.
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.
