A four green-light demultiplexer using a multi gallium nitride slot-waveguide structure
, 2020In this work, we introduce a four green-light wavelength splitter device, based on six slot-waveguide structures. Silica and gallium nitride materials were chosen for confining the green light inside the slot-waveguide area in a transverse magnetic field

Silicon slot waveguide Fano resonator
Optics Letters, 2018The growing interest for Fano resonators during the past decade is due to the narrow line shape observable in their optical spectra. The drastic phase shift occurring at the resonance yields a steep drop from a high to low amplitude. Fano resonances can be obtained by a combination of nanostructures.

Waveguide slot applicators for microwave heating
17th International Conference on Applied Electromagnetics and Communications, 2003. ICECom 2003., 2004In this paper we present an empirical procedure to design microwave slot array applicators for heating lossy dielectric slabs. To this end, a commercial simulation code has been used to characterize the behaviour of a slot radiating on a dielectric slab with a given complex permittivity.

This chapter investigates the properties of the modes supported by three-dimensional subwavelength plasmonic slot waveguides. It shows that the fundamental mode supported by a symmetric plasmonic slot waveguide, composed of a subwavelength slot in a thin metallic film embedded in an infinite homogeneous dielectric, is always a bound mode.

Waveguide matching crossed-slot
IEE Proceedings - Microwaves, Antennas and Propagation, 2003A matching crossed-slot, which is accommodated at the shorted end of a waveguide crossed-slot array and radiates all the residual power with circular polarisation in an array beam direction, is analysed and designed by the method of moments (MoM). The eigenmode functions for a crossed-slot derived numerically by the edge-based finite element method ...

TEM-modes In Slot-coupled Waveguides
27th European Microwave Conference and Exhibition, 1997TEM-modes which are usually expressed in terms of a scalar electric potential o are shown to be derivable from a scalar magnetic potential ? if the supporting transmission line can be considered a slot coupled waveguide with more than one coupling slot.

Plasmonic Slot Waveguides with Core Nonlinearity
Plasmonics, 2013We analytically study the interplay between group velocity dispersion and material dispersion due to femtosecond ultrafast pulse inside plasmonic slot waveguides with nonlinear dielectric core. The analytic investigation of the role of the core nonlinearity on pulse propagation has been investigated. Interestingly, our model shows that the focusing and
