Abstract
Official abstract text for this publication.
Various embodiments include large cores fibers that can propagate few modes or a single mode while introducing loss to higher order modes. Some of these fibers are holey fibers that comprise cladding features such as air-holes. Additional embodiments described herein include holey rods. The rods and fibers may be used in many optical systems including optical amplification systems, lasers, short pulse generators, Q-switched lasers, etc. and may be used for example for micromachining.
First claim
Opening claim text (preview).
What is claimed is: 1. An optical fiber for propagating at least one lower order mode having a wavelength λ, while limiting propagation of higher order modes having a wavelength λ by providing said higher order modes with a higher loss than said at least one lower order mode at said wavelength λ, said optical fiber comprising: a first cladding region comprising a plurality of holes having a diameter, d, and a center-to-center spacing, Λ, wherein the ratio d/Λ is larger than 0.4 an…
