By means of variational methods and systematic numerical analysis, we demonstrate the
existence of metastable solitons in three dimensional (3D) free space, in the context of …

The nonlinear coefficient of chalcogenide glass is 200–1000 times larger than that of silica
glass, and it is transparent in the 1–15 μm wavelength windows, which makes the nonlinear …

Abstract n this research paper under consideration is the nonlinear multi-core coupler
(coupling with all neighbors) with the parabolic law nonlinearity and optical metamaterials …

Modulation instability, breather formation, and the Fermi–Pasta–Ulam–Tsingou recurrence
(FPUT) phenomena are studied in this article. Physically, such nonlinear systems arise …

Modulation instability (MI) of cw states of a two-core fiber, incorporating the effects of
coupling-coefficient dispersion (CCD), is studied by solving a pair of generalized, linearly …

We present a phenomenological generalization of the standard model that describes the
propagation of electromagnetic waves in a nonlinear fiber equipped with the Bragg grating …

We introduce a mechanism to stabilize spatiotemporal solitons in Kerr nonlinear media,
based on the dispersion of linear coupling between the field components forming the soliton …

Modulational instability (MI) in a twin-core optical fiber with the combined effect of saturation
of nonlinearity (SNL) and coupling coefficient dispersion (CCD) is presented. The CCD does …

In this paper we did a study of logic gates obtained in the operation of a three-core non
linear directional coupler (TNLDC) and an asymmetric two-core coupler (DNLDC) operating …
