Spectral properties of limiting solitons in optical fibers [PDF]

, 2014
It seems to be self-evident that stable optical pulses cannot be considerably shorter than a single oscillation of the carrier field. From the mathematical point of view the solitary solutions of pulse propagation equations should loose stability or ...

Rhythmic Soliton Interactions for Integrated Dual-Microcomb Spectroscopy

Physical Review X
Soliton waves are sustained by a self-created index potential well, and their interactions occur when the potential well is invaded by other solitons. The interactions are important to soliton compounds in plasma, Bose-Einstein condensation, and optical ...

Discrete solitons in optical BEC lattices. Effects of n-body interactions [PDF]

, 2006
In this poster we show some recent results concerning discrete solitons in strong optical lattices, which can be described by the Discrete Nonlinear Schrödinger equation.

A study of optical solitons with Kerr and power law nonlinearities by He's variational principle [PDF]

, 2009
This paper studies optical solitons, in presence of perturbation terms, by the aid of He's variational principle. The inter-modal dispersion, self-steepening, nonlinear dispersion and Raman scattering are all treated as perturbation terms.

Dark spatial optical solitons in lithium niobate waveguides [PDF]

, 2001
We have realized dark spatial photovoltaic solitons at wavelength of 632.8 nm in Fe and Cu- doped planar optical waveguides in lithium niobate. It has been shown that for lowest TE modes the photovoltaic nonlinearity only partly compensated the light ...

Feasibility study for high bit rate pulse position modulation in fibre communications [PDF]

, 2013
With the rapid progress of optical communication systems, capacity limitation becomes important in high bit rate links. Overcoming this limitation may involve using different modulation and multiplexing methods, including RZ modulation with on-off keying

Soliton-effect optical pulse compression in CMOS-compatible ultra-silicon-rich nitride waveguides

APL Photonics, 2019
The formation of optical solitons arises from the simultaneous presence of dispersive and nonlinear properties within a propagation medium. Chip-scale devices that support optical solitons harness high field confinement and flexibility in dispersion ...
