TL;DR: This paper finds that the modes in an OmniGuide fiber are similar to those in a hollow metallic waveguide in their symmetries, cutoff frequencies, and dispersion relations, and shows that the differences can be predicted by a model based on a single parameter-the phase shift upon reflection from the dielectric mirror.

TL;DR: In this paper, a dielectric core region (110) extending along a waveguide axis was shown to have an average refractive index smaller than about 1.3 for a frequency in the first range of frequencies, and a diameter in a range between about 4μ and 80μ.

TL;DR: In this article, an optical waveguide has a workign mode with a tailored dispersion profile, the waveguide indlucing: (i) a dielectric confinement region surrounding a waveguide axis, comprising a photonic crystal having at least one photomic bandgap, wherein during operation the confinement region guides EM radiation in a first range of frequencies.

TL;DR: Three cases illustrating various applications of the OmniGuide flexible fiber CO2 laser system in the management of the patient with head and neck cancer are presented.

TL;DR: In this article, the authors developed a perturbation theory formulation to evaluate polarization-mode dispersion (PMD) for a general class of scaling perturbations of a waveguide profile based on generalized Hermitian Hamiltonian formulation of Maxwell's equations.
