We find specific wavepackets that overcome analogue gravitational phenomena due to the complex interplay between interference effects and various optical gravitational effects, and demonstrate them in experiments with nonlocal nonlinear interactions.
We introduce loss-proof shape-invariant nonparaxial accelerating beams that overcome both diffraction and absorption, and demonstrate their use in acceleration of microparticles inside liquids along curved trajectories that are significantly steeper than ever achieved.
Accelerating beams completely rely on interference: coherent superposition of waves. In spite of that fundamental feature, we demonstrate, experimentally and theoretically, partially-spatially-incoherent nonparaxial accelerating beams.
We demonstrate optical analogues of gravitational effects such as gravitational lensing, tidal forces and gravitational redshift in the Newton-Schrödinger mainframe, by utilizing long-range interactions between solitons and accelerating beams in nonlocal nonlinear media.
We introduce a new class of 1 & 2-dimensional beams that overcome both diffraction & absorption, enabling accelerating plasmons that maintain their intensity profile. In free space these beams exhibit a counterintuitive exponential intensity growth.
We present, theoretically and experimentally, non-broadening optical beams having arbitrarily small superoscillatory features. Our design facilitates control over the symmetry, width, and rotational orientation of the superoscillating beams.
We find self-accelerating beams in nonlocal nonlinear media and show that their propagation dynamics is affected by boundary conditions that increase their acceleration, or cause bending in a direction opposite to the initial trajectory.
