Stabilization of a (3+1)D soliton in a Kerr medium by a rapidly oscillating dispersion coefficient

, 2004
Using the numerical solution of the nonlinear Schroedinger equation and a variational method it is shown that (3+1)-dimensional spatiotemporal optical solitons can be stabilized by a rapidly oscillating dispersion coefficient in a Kerr medium with cubic ...

Tunable ultrafast nonlinear optofluidic coupler

EPJ Web of Conferences, 2013
We present an ultrafast nonlinear coupler fabricated by selectively filling of two strands of a PCF with the liquid CCl4 which exhibits a large Kerr nonlinearity. We demonstrate power dependent switching in this optofluidic device.

Waveguides with Absorbing Boundaries: Nonlinearity Controlled by an Exceptional Point and Solitons

, 2017
We reveal the existence of continuous families of guided single-mode solitons in planar waveguides with weakly nonlinear active core and absorbing boundaries.

Asymmetrical temporal dynamics of edge modes in Su-Schrieffer-Heeger lattice with Kerr nonlinearity

Physical Review Research
Optical bistability and oscillating phases exist in a Sagnac interferometer and a single ring resonator made of a χ^{(3)} nonlinear medium where the refractive indices are modulated by the light intensity due to the Kerr nonlinearity. An array of coupled

Third-order nonlinear optical properties of bismuth-borate glasses measured by conventional and thermally managed eclipse Z scan

, 2007
Third-order nonlinearity one order of magnitude larger than silica is measured in bismuth-borate glasses presenting a fast response (<200 fs). The results for the sign and magnitude of the nonlinearity were obtained using a combination of the eclipse ...

Nonlinear Optics Quantum Computing with Circuit-QED

, 2012
One approach to quantum information processing is to use photons as quantum bits and rely on linear optical elements for most operations. However, some optical nonlinearity is necessary to enable universal quantum computing.

Pulse Shaping in Hybrid Waveguides with the High-Order Kerr Nonlinearity

Photonics
Kerr nonlinear effect extremely impacts both the spectral and the temporal evolutions of ultrashort pulses, although it is challenging to tailor over a broadened spectral region.

Entanglement concentration for arbitrary four-particle linear cluster states

Scientific Reports, 2017
Cluster states, whose model are a remarkably rich structure in measurement-based quantum computation, hold high degree of entanglement, while entanglement is very fragile during the process of transmission because of the inevitable interaction with the ...

Optical vortices in dispersive nonlinear Kerr‐type media [PDF]

International Journal of Mathematics and Mathematical Sciences, 2004
The applied method of slowly varying amplitudes gives us the possibility to reduce the nonlinear vector integrodifferential wave equation of the electrical and magnetic vector fields to the amplitude vector nonlinear differential equations. Using this approximation, different orders of dispersion of the linear and nonlinear susceptibility can be ...
