We propose a broadband plasmonic logic source, which is a nanostructure composed of two parallel plasmonic gap waveguides coupled with dual square ring resonators aligned in a vertical or horizontal manner. The numerical simulations show that this configuration has up to 3-bit logic combinations for three output ports when the input port is illuminated with the combination of white sources and different...
Plasmonic gap waveguides allow for subwavelength integration of optical circuitry. A side effect is extraordinarily high field enhancement. Here we present experimental and numeric results, which indicate nonlinear switching in a directional coupler.
In this paper, a general model of nonlinearly stochastically coupled network with two types of time-varying delays is proposed. The network model is subject to stochastic disturbance described by Wiener process in the nonlinear coupling term. The two types of time-varying delays are the system delay in the nodes dynamics and the coupling delay between nodes. By employing the stochastic It differential...
We experimentally demonstrate the excitation of plasmonic gap waveguides by nano antennas. The excitation is shown to be both spatially and spectrally dependent which can potentially be used for the selective excitation of plasmonic nanostructures.
