Squeezing and entanglement of matter-wave gap solitons [PDF]
, 2004 We study quantum squeezing and entanglement of gap solitons in a Bose-Einstein condensate loaded into a one-dimensional optical lattice. By employing a linearized quantum theory we find that quantum noise squeezing of gap solitons, produced during their ...

Dirac solitons in optical microresonators [PDF]
Light: Science & Applications, 2020 AbstractMode-coupling-induced dispersion has been used to engineer microresonators for soliton generation at the edge of the visible band. Here, we show that the optical soliton formed in this way is analogous to optical Bragg solitons and, more generally, to the Dirac soliton in quantum field theory. This optical Dirac soliton is studied theoretically,

Phase shift, amplification, oscillation and attenuation of solitons in nonlinear optics
Journal of Advanced Research, 2019 In nonlinear optics, the soliton transmission in different forms can be described with the use of nonlinear Schrödinger (NLS) equations. Here, the soliton transmission is investigated by solving the NLS equation with the reciprocal of the group velocity ...

Lattice-supported surface solitons in nonlocal nonlinear media [PDF]
, 2006 We reveal that lattice interfaces imprinted in nonlocal nonlinear media support surface solitons that do not exist in other similar settings, including interfaces of local and nonlocal uniform materials.

Optical solitons in fibre Bragg gratings with third- and fourth-order dispersive reflectivities
Ukrainian Journal of Physical Optics, 2021 . For the first time in the field of nonlinear optics, we address cubic–quartic solitons appearing in the fibre Bragg gratings with dispersive reflectivity for four different cases of nonlinear refractive-index structures.

Optical Soliton Neural Networks
, 2023 The chapter describes the realization of photonic integrated circuits based on photorefractive solitonic waveguides. In particular, it has been shown that X-junctions formed by soliton waveguides can learn information by switching their state. X junctions can perform both supervised and unsupervised learning.

Stability of Multihump Optical Solitons [PDF]
Physical Review Letters, 1999 We demonstrate that, in contrast with what was previously believed, multi-hump solitary waves can be stable. By means of linear stability analysis and numerical simulations, we investigate the stability of two- and three-hump solitary waves governed by incoherent beam interaction in a saturable medium, providing a theoretical background for the ...
