Zoned optical fibre

Zoned optical fibre

An optical fibre 400 (500; 600; 700; 900; 1000) comprising a core 410 (510; 610; 910; 1010) and at least one cylinder 450 455 (550, 555; 650, 655; 755; 950, 955; 1050, 1055) together forming a plurality of zones. In use, the zones have a primary optical function of confining light within the fibre 4...

Zusammenfassung:An optical fibre 400 (500; 600; 700; 900; 1000) comprising a core 410 (510; 610; 910; 1010) and at least one cylinder 450 455 (550, 555; 650, 655; 755; 950, 955; 1050, 1055) together forming a plurality of zones. In use, the zones have a primary optical function of confining light within the fibre 400 (500; 600; 700; 900; 1000). Successive zones have different refractive indices and different widths. At least one of the zones comprises a material that exhibits a second optical function such as optical gain or controllable refractive index.
