Perfectly Conducting Graphene Electronic Waveguide with Curved Channels [PDF]
, 2017 We theoretically investigate the electronic transport properties of curved graphene waveguides by employing non-equilibrium Green's function techniques. We systematically study the dependence of the confined waveguide modes on the potential difference, the width of waveguide and side barrier.

Metamaterial Loadings for Waveguide Miniaturization [PDF]
J. Appl. Phys. 114, 214901 (2013), 2013 We show that a rectangular metallic waveguide loaded with metamaterial elements consisting of electric-field coupled (ELC) resonators placed at the side walls can operate well below the cutoff frequency of the respective unloaded waveguide. The dispersion diagrams indicate that propagating modes in ELC-loaded waveguides are of forward-type for both TE ...

Refractive index sensor based on slot waveguide cavity [PDF]
Journal of the European Optical Society-Rapid Publications, 2012 The experimental study of a gold slot waveguide cavity is presented. The resonance of this cavity working in the telecom wavelength range is highly dependent on the refractive index of the medium located in or around the slots array, because of the high ...

Enhanced optical Kerr nonlinearity of graphene/Si hybrid waveguide [PDF]
, 2018 In this work, we experimentally study the optical kerr nonlinearities of graphene/Si hybrid waveguides with enhanced self-phase modulation. In the case of CMOS compatible materials for nonlinear optical signal processing, Si and silicon nitride waveguides have been extensively investigated over the past decade. However, Si waveguides exhibit strong two-

Quantum entanglement in plasmonic waveguides with near-zero mode indices [PDF]
Optics Letters, Vol. 38, Issue 20, pp. 4078-4081 (2013), 2013 We investigate the quantum entanglement between two quantum dots in a plasmonic waveguide with near-zero mode index, considering the dependence of concurrence on interdot distance, quantum dot-waveguide frequency detuning and coupling strength ratio.

Coupled-resonator optical waveguide: a proposal and analysis.
Optics Letters, 1999 We propose a new type of optical waveguide that consists of a sequence of coupled high-Q resonators. Unlike other types of optical waveguide, waveguiding in the coupled-resonator optical waveguide (CROW) is achieved through weak coupling between ...
