Modifying the optical path in a nonlinear double-slit experiment
Vassilis Paltoglou, Nikolaos K. Efremidis
In this letter, we study a nonlinear interferometric setup based on diffraction rather than beam combining. It consists of a nonlinear analogue of Young's double-slit experiment wh…
Closed-form expressions for nonparaxial accelerating beams with pre-engineered trajectories
Raluca-Sorina Penciu, Vassilis Paltoglou, Nikolaos K. Efremidis
In this letter, we propose a general real-space method for the generation of nonparaxial accelerating beams with arbitrary predefined convex trajectories. Our results lead to close…
Composite multi-vortex diffraction-free beams and van Hove singularities in honeycomb lattices
Vassilis Paltoglou, Zhigang Chen, Nikolaos K. Efremidis
We find diffraction-free beams for graphene and MoS-type honeycomb optical lattices. The resulting composite solutions have the form of multi-vortices, with spinor topological…
