Plasmonic waveguides cladded by hyperbolic metamaterials [PDF]

open access: yesOptics Letters, Vol. 39, Issue 16, pp. 4663-4666 (2014), 2014
Strongly anisotropic media with hyperbolic dispersion can be used for claddings of plasmonic waveguides. In order to analyze the fundamental properties of such waveguides, we analytically study 1D waveguides arranged of a hyperbolic metamaterial (HMM) in a HMM-Insulator-HMM (HIH) structure.

Waveguiding properties of surface states in photonic crystals [PDF]

open access: yes, 2005
We propose and analyze novel surface-state-based waveguides in bandgap photonic crystals. We discuss surface mode band structure, field localization and effect of imperfections on the waveguiding properties of the surface modes. We demonstrate that surface-state-based waveguides can be used to achieve directional emission out of the waveguide.

Birefringence compensation in double-core optical waveguides [PDF]

open access: yes, 1998
A new concept for birefringence compensation in planar optical waveguides applying a double-core structure is introduced. It is demonstrated on waveguides fabricated in silicon oxynitride technology for applications in optical ...

The overlap is not a waveguide [PDF]

open access: yesPhysics Letters B, 1995
Golterman and Shamir falsely claim that a waveguide model modified by adding many charged bosonic spinors, in the limit of an infinite number of matter fields, becomes identical to the overlap if in the target theory every fermion appears in four copies.

Dimensional Transformations of Guided-Mode Resonant Photonic Lattices

open access: yesIEEE Photonics Journal, 2020
Reflection spectra based on guided-mode resonance (GMR) are simulated and discussed with transformation between one-dimensional (1-D) and two-dimensional (2-D) photonic lattices by introducing intermediate structures consisting of vertically-stacked 1-D ...
