We show that high-intensity Airy pulses propagating in Kerr-type nonlinear media can preserve their self-accelerating features under appropriate conditions. By engineering the input pulses, controllable spectral shifting and reshaping are achieved.
We demonstrate optical beam auto-focusing without the need of a focusing lens or nonlinearity. Radial Airy beams with inward and outward accelerations are used and an abrupt transition between Airy and Bessel behavior is observed.
We demonstrate an induction technique to generate honeycomb photonic lattices with equal and unequal sites in each unit-cell. We show light localization as nonlinear solitons and linear Shockley surface states in lattices with unequal sites.
We generate optical beams with rotating intensity blades, namely “optical propellers”, by employing Moiré technique. Such rotating beams are controlled by SLM without mechanical movement or phase-sensitive interference. Self-trapping of propelling beams is also demonstrated.
