Corning Inc Files Patent Application for Method for Producing Optical Fiber Having Controlled Index Perturbations

Corning Inc filed the patent application on Feb. 4, 2014. The patent application number is 817/DELNP/2014 A. The international classification number is C03B37/027.

According to the Controller General of Patents, Designs & Trade Marks, "A method for producing an optical fiber is provided. The method includes the steps of drawing an optical fiber from a heated glass source in a furnace and introducing index perturbations to the optical fiber via a plurality of perturbation sources arranged at a plurality of different azimuthal locations. The index perturbations are introduced synchronously at different locations along the axial length of the fiber by the plurality of perturbation sources in a generally helical pattern on the outside surface of the fiber in one embodiment. According to another embodiment the index perturbations are introduced by the plurality of perturbation sources at different frequencies."

The Patent was published in the Issue No. 02/2015 of the Patent Office Journal on Jan. 9, 2015.
