Cross-phase modulation mediated pulse control with Airy pulses in optical fibers
Michael Goutsoulas, Vassilis Paltoglou, Nikolaos K. Efremidis
We show that the velocity and thus the frequency of a signal pulse can be adjusted by the use of a control Airy pulse. In particular, we utilize a nonlinear Airy pulse which, via c…
Parity breaking with a nonlinear optical double-slit configuration
Vassilis Paltoglou, Nikolaos K. Efremidis
We consider an optical nonlinear interferometric setup based on Young's double-slit configuration where a nonlinear material is placed exactly after one of the two slits. We examin…
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…
Unveiling pseudospin and angular momentum in photonic graphene
Daohong Song, Vassilis Paltoglou, Sheng Liu +7
Pseudospin, an additional degree of freedom inherent in graphene, plays a key role in understanding many fundamental phenomena such as the anomalous quantum Hall effect, electron c…
Strain-induced interface reconstruction in epitaxial heterostructures
N. Lazarides, V. Paltoglou, P. Maniadis +2
We investigate in the framework of Landau theory the distortion of the strain fields at the interface of two dissimilar ferroelastic oxides that undergo a structural cubic-to-tetra…
Nonlinear magnetoinductive transmission lines
Nikos Lazarides, Vassilis Paltoglou, G. P. Tsironis
Power transmission in one-dimensional nonlinear magnetic metamaterials driven at one end is investigated numerically and analytically in a wide frequency range. The nonlinear magne…
