Patent number: 11982834Abstract: A microstructured optical fiber for generating supercontinuum light. The optical fiber includes a core and a cladding region surrounding the core. The optical fiber includes a first fiber length section, a second fiber length section as well as an intermediate fiber length section between said first and second fiber length sections. The first fiber length section has a core with a first characteristic core diameter larger than about 7 ?m. The second fiber length section has a core with a second characteristic core diameter, smaller than said first characteristic core diameter. The intermediate length section of the optical fiber includes a core which is tapered from said first characteristic core diameter to the second characteristic core diameter over a tapered length. Also, a supercontinuum light source including an optical fiber and a pump light source.Type: GrantFiled: December 8, 2021Date of Patent: May 14, 2024Assignee: NKT PHOTONICS A/SInventors: Carsten L.

Publication number: 20030173772Abstract: This invention relates to an advertisement print being printed on a substantially plane print carrier. The print is a transformation of a chosen three-dimensional geometrical element having a number of visible sides defined by at least a first viewpoint and a second viewpoint. The sides are combined and the print can optimally be viewed from two different viewpoints, even though they are pointing in opposite directions. The invention is e.g. especially advantageous in cricket games and the like, where the game is typically broadcasted using two or more main cameras pointing in substantially opposite directions.Type: ApplicationFiled: March 13, 2002Publication date: September 18, 2003Inventors: Erik B.
