We report on a direct visualization of coherent destruction of tunneling (CDT) of light waves
in a double well system which provides an optical analog of quantum CDT as originally …

Two different approximations for the propagation constant of a guided mode in a rectangular
dielectric waveguide can be obtained by applying the conventional effective-index method …

This paper presents a novel tunable terahertz antenna based on a hybrid graphene-metal
structure fed by a waveguide. First, the hybrid plasmonic waveguide is studied by analytical …

The optical properties of slab-like photonic crystals are often discussed on the basis of
effective index (EI) approximations, where a 2-D effective refractive index profile replaces …

A method for calculating the modes of arbitrarily shaped dielectric waveguides is presented.
It consists of expanding the field in a two-dimensional Fourier series. The expansion is used …

This article describes a model and the process technology of realizing fused fiber coupler-
based branching components through the use of an experimental setup of a PC-controlled …

An asymptotic study of the effective-index method for the analysis of rectangular-core
dielectric waveguides is given. Two ways of applying the effective-index method, depending …

Rib channel waveguides were produced with the application of chemical wet etching of the
sol-gel derived silica–titania (SiO 2–TiO 2) waveguide films. The silica–titania films were …
