Large effective area waveguide fiber

摘要

A single mode optical waveguide fiber having a segmented core designed to provide a large effective area for light transmission. The large effective area reduces waveguide fiber non-linearities. The inventive waveguide is thus suited for transmission of high power signals over long distances.Embodiments of the inventive single mode waveguide including five core segments are given. The large effective area is achieved with essentially no degradation in optical or mechanical performance of the waveguide.
