Financiado para publicación en acceso aberto: Universidade de Vigo/CISUG We study topologically charged propagation-invariant eigenstates of the 1+2-dimensional Schrödinger equation with a cubic (focusing)–quintic (defocusing) nonlinear term. Fir

We propose an ultracompact nonlinear plasmonic directional coupler for switching of ultrashort optical pulses. We show that this device can be used to control the routing of ultrashort pulses using either the energy or the duration of each individual

ZnO has been demonstrated to be a promising material for optoelectronic applications in the terahertz (THz) spectral range. However, there have been no reports regarding the fabrication of ZnO structures to control THz radiation, as photonic crystal

We study switching operation in a plasmonic coupler using fs-pulses. Simulations using the finite difference time-domain method (FDTD) are carried out showing how the output changes as the pulse energy increases raising from zero to a maximum. Both c

We present a system able to discriminate pulses according to their duration with potential applications in all-optical signal multiplexing. The device is based on a directional coupler with nonlinear cores and metallic claddings with dimensions in a

We study the self-trapped vortex-ring eigenstates of the two-dimensional Schr\"odinger equation with focusing Poisson and cubic nonlinearities. For each value of the topological charge $l$, there is a family of solutions depending on a parameter that

We study a plasmonic directional coupler with a metallic cladding and dielectric core in the presence of balanced gain and loss, and demonstrate that such a photonic structure can possess the parity-time (PT) symmetry even when optical losses in meta
