Abstract

Zgłoszenie dotyczy światłowodu z kształtowanym profilem fotoczułości zawierającym nanostrukturyzowany rdzeń, złożony z co najmniej dwóch rodzajów pręcików szklanych, przy czym co najmniej jeden rodzaj pręcików szklanych jest domieszkowanych germanem. Zgłoszenie dotyczy także sposobu wytwarzania światłowodu o rdzeniu zawierającym umożliwiającym wytwarzanie fotoindukowanej modulacji współczynnika załamania. W zależności od konkretnego typu takie światłowody znajdują zastosowanie m.in. w generacji laserowej i w technikach wzmocnienia (światłowody aktywne) i/lub w czujnikach światłowodowych i zastosowaniach telekomunikacyjnych (światłowody pasywne).
