Efficient optical energy harvesting in self-accelerating beams
journal contribution
posted on 2023-06-09, 02:53 authored by Domenico Bongiovanni, Yi Hu, Benjamin Wetzel, Raul A Robles, Gregorio Mendoza González, Erwin A Marti-Panameño, Zhigang Chen, Roberto MorandottiWe report the experimental observation of energetically confined self-accelerating optical beams propagating along various convex trajectories. We show that, under an appropriate transverse compression of their spatial spectra, these self-accelerating beams can exhibit a dramatic enhancement of their peak intensity and a significant decrease of their transverse expansion, yet retaining both the expected acceleration profile and the intrinsic self-healing properties. We found our experimental results to be in excellent agreement with the numerical simulations. We expect further applications in such contexts where power budget and optimal spatial confinement can be important limiting factors.
