چکیده
Using the numerical solution of the nonlinear Schrödinger equation and a variational method, it is shown that ( 3+1 ) -dimensional spatiotemporal optical solitons, known as light bullets, can be stabilized in a layered Kerr medium with sign-changing nonlinearity along the propagation direction.

Stabilization of a (3+1)-dimensional soliton in a Kerr medium by a rapidly oscillating dispersion coefficient.
Using the numerical solution of the nonlinear Schrödinger 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 nonlinearity. This has immediate consequence in generating dispersion-managed robust optical soliton in communication as well as possible stabil...
متن کاملControl of Squeezed Light Pulse Spectrum in the Kerr Medium with an Inertial Nonlinearity
The consistent quantum theory of self-phase modulation (SPM) and cross-phase modulation (XPM) for ultrashort light pulses (USPs) in medium with electronic Kerr-nonlinearity are developed. The approach makes use of momentum operator of electrical field which takes account of the inertial behaviour of the nonlinearity. The spectrum of quantum fluctuations of squeezed-quadrature component as a fun...
متن کاملSpatial solitons in a medium composed of self-focusing and self-defocusing layers
We introduce a model combining Kerr nonlinearity with a periodically changing sign (“nonlinearity management”) and a Bragg grating (BG). The main result, obtained by means of systematic simulations, is presented in the form of a soliton’s stability diagram on the parameter plane of the model; the diagram turns out to be a universal one, as it practically does not depend on the soliton’s power. ...
متن کاملMeasurement-Induced Strong Kerr Nonlinearity for Weak Quantum States of Light.
Strong nonlinearity at the single photon level represents a crucial enabling tool for optical quantum technologies. Here we report on experimental implementation of a strong Kerr nonlinearity by measurement-induced quantum operations on weak quantum states of light. Our scheme coherently combines two sequences of single photon addition and subtraction to induce a nonlinear phase shift at the si...
متن کاملM ay 2 01 0 Analytical theory of dark nonlocal solitons
Spatial dark optical solitons are localized light intensity dips in the infinite constant background [1–3]. Like their bright counterparts, they propagate preserving their spatial profile. This is a result of a balance between diffraction which tends to broaden their size and nonlinearity of the medium which counteracts this process. The existence of dark spatial solitons requires the nonlinear...
