Abstract
The invention relates to an optical fiber as an optical waveguide for the single-mode operation. The present invention proposes a fiber having a microstructure, by which the propagation of modes of a higher order are selectively suppressed in the optical waveguide. At the same time, the propagation of transversal modes of a higher order is dampened more strongly than the propagation of the fundamental modes of the optical waveguide.
Claims23
Optical fiber as an optical waveguide for single-mode operation, wherein the fiber has a structuring by means of which propagation of higher order modes in the optical waveguide is selectively suppressed.
