Abstract: Abstract We show the existence of nonlinear resonant states in a higher-order nonlinear Schrodinger model that appertains to the wave propagation in femtosecond fiber optics, under certain parametric regime. These nonlinear resonant states are analytically… read more here.

DOI: 10.3390/app10082678
Abstract: Inspired by the self-cleaning and water-repellent lotus leaf, we have developed an efficient process to create superhydrophobic metal surfaces using a femtosecond fiber laser and have investigated the mechanisms of the structured metal surfaces in… read more here.
