Electromagnetic metamaterials, artificial media created by subwavelength structuring, are
useful for engineering electromagnetic space and controlling light propagation. Such …

Several classes of non-planar metallic and dielectric waveguides have been proposed in
the literature for guidance of terahertz (THz) or T-ray radiation. In this review, we focus on the …

The field of hybrid optical fibers is one of the most active research areas in current fiber
optics and has the vision of integrating sophisticated materials inside fibers, which are not …

This paper reviews the topic of microstructured polymer fibres in the fields in which these
have been utilised: microstructured optical fibres, terahertz waveguides, and fibre‐drawn …

A key requirement for achieving high-density integration of terahertz (THz) systems is a
strongly confining single-mode and low-loss waveguide. Several waveguide solutions …

Nonlinear optical processes, which are of paramount importance in science and technology,
involve the generation of new frequencies. This requires phase matching to avoid that light …

Internal physical structure can drastically modify the properties of waveguides: photonic
crystal fibers are able to confine light inside a hollow air core by Bragg scattering from a …

Manmade media (MMMs) consisting of uniaxial photonic crystals with inserts of layers (films)
or cylinders embedded in a periodic way into a dielectric substrate with dielectric …

We present a comprehensive study of the effect of material dispersion on the guided modes
of a circular waveguide with an anisotropic, uniaxial metamaterial cladding, including in …

Fibre drawing is used to fabricate indefinite media based on wire array metamaterials.
Fibres containing arrays of indium wires embedded in polymer are drawn using an optical …
