Spectral optimization of supercontinuum shaping using metaheuristic algorithms, a comparative study

Scientific Reports
Supercontinuum generation in optical fiber involves complex nonlinear dynamics, making optimization challenging, and typically relying on trial-and-error or extensive numerical simulations.

Thermal Conductivity of Iron at the Conditions of Small Planetary Cores

Journal of Geophysical Research: Planets, Volume 131, Issue 10, October 2026.
Abstract Planetary interiors cool and evolve over geologic time, and their thermal evolution depends on heat transport through their constituent layers. Here, the thermal conductivity of iron has been measured between 19 and 65 GPa and between 1700 and 2500 K in order to constrain its value at the conditions of small planetary cores.

Initial development of supercontinuum in fibers with anomalous dispersion pumped by nanosecond - long pulses [PDF]

, 2008
We propose and compare with experimental data a two-stage model of supercontinuum formation in a fiber for nanosecond-long pulse with intensities in 10W range. As a result of the first stage, the sea of solitons is formed.

Directional supercontinuum generation

, 2018
Directional supercontinuum is generated in a silicon-rich nitride waveguide with two zero dispersion wavelengths. The supercontinuum is caused by interaction between a soliton and a pulse in the normal dispersion regime leading to dispersive ...

RGB generation in secondary cores of microstructured fibres

Generation of white laser light in the visible regime currently attracts a lot of attention. Optical-fibre-based solutions have so far been presented by supercontinuum generation in tapered fibres and small-core microstructured holey fibres.
