Transformation from Self-Focusing to Self-Defocusing of Silver Nanoparticles
J Jiang, Y Jia, T Wu, Y Gao - Nanomaterials, 2021 - mdpi.com
The nonlinear refraction of silver nanoparticles (AgNPs) in n-hexane was studied by using
the closed-aperture Z-scan technique with a 532 nm nanosecond laser. It was found that, the …

Four-wave mixing and enhanced analog Hawking effect in a nonlinear optical waveguide
We study in detail the scattering of light on a soliton propagating in a waveguide which has
been proposed as an experimental system in which one could observe the analog Hawking …

All-optical control of fiber solitons
S Pickartz - 2018 - edoc.hu-berlin.de
This work discusses the problem how to control an optical soliton propagating along a non-
linear fiber. The approach chosen here is to change soliton delay, duration and intensity in a …
