Effects of Kerr Nonlinearity in Physical Unclonable Functions

Applied Sciences, 2022
We address the question of whether the presence of Kerr nonlinearity in multiple-scattering optical media offers any advantage with respect to the design of physical unclonable functions. Our results suggest that under certain conditions, nonlinear physical unclonable functions can be more robust against the potential cloning of the medium relative to ...

Optical branched flow in nonlocal nonlinear medium

Nanophotonics
When light propagates through a randomly correlated, slowly varying medium, it generates optical branched flow. Previous studies have demonstrated that the self-focusing effect in optical media can accelerate the appearance of the first branching points ...

Intermodal all-optical pulse switching and frequency conversion using temporal reflection and refraction in multimode fibers

Nanophotonics
In this work, we extend temporal reflection and refraction analogies from the case of singlemode optical fibers to multimode fibers. Specifically, we show that nonlinear multimode fibers provide novel degrees of freedom that permit us to control optical ...

Passive Q-switching of an all-fiber laser induced by the Kerr effect of multimode interference.

Optics Express, 2015
A novel passively Q-switched all-fiber laser using a single mode-multimode-single mode fiber device as the saturable absorber based on the Kerr effect of multimode interference is reported.

Magnetised Kerr/CFT correspondence

Physics Letters B, 2015
The tools of Kerr/CFT correspondence are applied to the Kerr black hole embedded in an axial external magnetic field. Its extremal near horizon geometry remains a warped and twisted product of AdS2×S2.

The band structures of three-dimensional nonlinear plasma photonic crystals

AIP Advances, 2018
In this paper, the properties of the photonic band gaps (PBGs) for three-dimensional (3D) nonlinear plasma photonic crystals (PPCs) are theoretically investigated by the plane wave expansion method, whose equations for calculations also are deduced.

All optical 1 to 2 decoder based on photonic crystal ring resonator [PDF]

Journal of Optoelectronical Nanostructures, 2017
In this paper we combined an optical mixer via photonic crystal ringresonator to propose an all optical 1 to 2 decoder. The main idea used in this paper isbased on controlling the optical behavior of the resonant ring via optical powerintensity.

Researching on Hawking Effect in a Kerr Space Time via Open Quantum System Approach

Advances in High Energy Physics, 2014
It has been proposed that Hawking radiation from a Schwarzschild or a de Sitter spacetime can be understood as the manifestation of thermalization phenomena in the framework of an open quantum system.
