Control of Airy-beam self-acceleration by photonic lattices
(Physical Review A, 2014)
We demonstrate control over the acceleration of two-dimensional Airy beams propagating in optically induced photonic lattices. Depending on the lattice strength, we observe a slowing-down and suppression of the self-acceleration ...
Defect-guided Airy beams in optically induced waveguide arrays
(Physical Review A, 2013)
We demonstrate both theoretically and experimentally that a finite Airy beam changes its trajectory and shape in optically induced waveguide arrays consisting of different kinds of defects. The propagation dynamics and ...
