We theoretically show that it is possible to generate diffraction-resisting higher order Bessel beams with vortex profiles that follow arbitrary trajectories. Our theoretical results are supported by numerical simulations and agree well with experimental observations.
Optical beams of the Bessel-type can counteract diffraction and thus maintain their profile during propagation and for this reason they have attracted considerable attention [1]. In terms of applications, Bessel beams have been studied in connection to particle manipulation, filamentation, and microscopy among others [2]. Such beams follow straight trajectories even though waves with Bessel-like profile...
We theoretically and experimentally demonstrate self-accelerating Bessel-like optical beams propagating along arbitrary trajectories in free space. Such beams possess nearly symmetric nondiffracting main lobes and exhibit self-healing properties, promising for a variety of applications.
We demonstrate theoretically and experimentally that optical vortices can be navigated along arbitrary trajectories with a preserving donut-shaped main lobe. The possibility of using such self-accelerating vortex-Bessel-like optical beams for particle manipulation is also illustrated.
We present self-accelerating self-trapped beams in self-focusing and self-defocusing Kerr and saturable media. Such beams are stable under self-defocusing and weak self-focusing, whereas for strong self-focusing they off-shoot solitons while their main lobe continues accelerating.
