An All-Dielectric Coaxial Waveguide.
TLDR
An all-dielectric coaxial waveguide that can overcome problems of polarization rotation and pulse broadening in the transmission of optical light is presented here.Abstract:Â
An all-dielectric coaxial waveguide that can overcome problems of polarization rotation and pulse broadening in the transmission of optical light is presented here. It consists of a coaxial waveguiding region with a low index of refraction, bounded by two cylindrical, dielectric, multilayer, omnidirectional reflecting mirrors. The waveguide can be designed to support a single mode whose properties are very similar to the unique transverse electromagnetic mode of a traditional metallic coaxial cable. The new mode has radial symmetry and a point of zero dispersion. Moreover, because the light is not confined by total internal reflection, the waveguide can guide light around very sharp corners.read more

Wavelength-scalable hollow optical fibres with large photonic bandgaps for CO 2 laser transmission
TL;DR: The design and drawing of a hollow optical fibre lined with an interior omnidirectional dielectric mirror is reported, demonstrating that low attenuation can be achieved through structural design rather than high-transparency material selection.
Journal ArticleDOI
Antiresonant reflecting photonic crystal optical waveguides.
TL;DR: A new regime of guidance is identified in which the spectral properties of these structures are largely determined by the thickness of the high-index layers and the refractive-index contrast and are not particularly sensitive to the period of the cladding layers.
