Waveguide containing a backward‐wave slab [PDF]
Radio Science, 2003 We have considered theoretically the waveguide properties of a plane two‐layered waveguide, whose one layer is a usual magnetodielectric (forward‐wave medium), but another one is a slab of so‐called backward‐wave material (BW‐material), whose both permittivity and permeability are negative.

Reflectivity of buried slab waveguides
Journal of the Optical Society of America A, 2004 The scattering properties of an abruptly ended buried slab waveguide for both TE and TM modes are examined by an improved iteration technique that is based on the integral equation method with "accelerating" parameters. The waveguide is considered a symmetrical slab, for which the weakly guiding conditions are invalid, and it is embedded in a different

A Theoretical Description of Node-Aligned Resonant Waveguide Gratings
Optics, 2022 Waveguide gratings are used for applications such as guided-mode resonance filters and fiber-to-chip couplers. A waveguide grating typically consists of a stack of a single-mode slab waveguide and a grating. The filling factor of the grating with respect

Guided-mode triggered switching between TE orders of a metal-based grating-waveguide [PDF]
Journal of the European Optical Society-Rapid Publications, 2015 An undulated metal-based dielectric slab waveguide is shown to exhibit a high contrast broadband switching effect in the angular spectrum between the 0th order Fresnel reflection and the propagating -1st reflected diffraction orders.

Coupling of quantum-well emission to waveguide–plasmon polaritons in rolled-up microtubes
APL Photonics, 2020 We study the coupling of GaAs quantum wells to waveguide–plasmon polaritons supported by a thin InAlGaAs-based slab waveguide and a Ag grating. The hybrid photon–plasmon modes are excited in a freestanding emitter–waveguide–plasmon structure realized by ...

Re-analysis of single-mode conditions for thin-film lithium niobate rib waveguides
Results in Physics, 2021 Single-mode waveguide devices are necessary in photonic integrated circuits. Previous studies on the single-mode conditions (SMCs) of the thin film lithium niobate (TFLN) either only focus on wire waveguide, or lack comprehensive discussions on the ...

Line Defect-Layered EBG Waveguides in Dielectric Substrates
International Journal of Antennas and Propagation, 2018 A dielectric-based multilayer structure composed of U-shaped rings (ML-UR) is used to develop a class of novel electromagnetic band gap (EBG) slab waveguide. The structure has two band gaps that narrow down as dielectric constant is increased.
