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. Thomsen, Thomas T. Alkeskjold, Erik B. Thomsen
