Reflectivity of buried slab waveguides

open access: yesJournal 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

Magnetohydrodynamic Waves in Multi-Layered Asymmetric Waveguides: Solar Magneto-Seismology Theory and Application

open access: yesFrontiers in Astronomy and Space Sciences, 2019
Diagnosing the solar atmospheric plasma is one of the major challenges in solar physics. Magnetohydrodynamic (MHD) waves, by means of applying the powerful concept of solar magneto-seismology (SMS), provide a tool to obtain diagnostic insight into the ...

Design of a Slab Tamm Plasmon Resonator Coupled to a Multistrip Array Waveguide for the Mid Infrared

open access: yesSensors, 2022
In this work, we present and analyze a design of an absorber–waveguide system combining a highly sensitive waveguide array concept with a resonant selective absorber. The waveguide part is composed of an array of coupled strip waveguides and is therefore

The Features of The Hyperbolic Slab Waveguide [PDF]

open access: yesEPJ Web of Conferences, 2015
The dispersion relation determining guided TE and TM modes are found for the slab hyperbolic waveguide. The waveguide is consisting of an isotropic dielectric slab bounded by hyperbolic media. Some differences between the features of the waveguide under consideration and conventional ones are obtained. In particular, in the case of hyperbolic waveguide

Propagation in rectangular waveguides with a pseudochiral Omega slab

open access: yesJournal of Telecommunications and Information Technology, 2002
The transfer matrix approach is applied for analysis of waveguides loaded with a uniaxial pseudochiral Omega slab. In particular a pseudochiral parallel plate and rectangular guides are investigated.

Shallow etched low-loss thin film lithium niobate waveguides with bound states in the continuum

open access: yesAIP Advances, 2023
Thin film lithium niobate (TFLN) features a small photonic device footprint and excellent optical properties. Despite the recent progress on plasma-etched TFLN waveguides, scattering loss induced by the sidewall roughness still limits the performance of ...

Evanescent Wave Sensitivity of Silica-Titania Rib Waveguides in the Single-Mode Propagation Regime

open access: yesPhotonics, 2023
The analysis reported in this paper shows that the homogeneous sensitivity of both fundamental rib waveguide modes, HE00 and EH00, can slightly exceed the sensitivity of the optimized parent slab waveguide.

Line Defect-Layered EBG Waveguides in Dielectric Substrates

open access: yesInternational 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.
