Dynamics of Airy beams in parity–time symmetric optical lattices
Chen Rui-Hong1, Hong Wei-Yi2, †
       

The evolutions of the Airy beam in the PT lattices in the linear regime with (a) V0=0.2, (b) V0=0.5, (c) V0=0.7, and (d) V0=1. The band structures (first two bands) for the cases of (e) V0=0.2, (f) V0=0.5, (g) V0=0.7, and (h) V0=1. The other parameter is set as ω=1.
