Abstract
A method of making a microstructured optical fiber including loading the core and cladding materials of the fiber with hydrogen and deuterium at a loading temperature; annealing the fiber at a selected temperature Tanneal; pumping the fiber with radiation; and reducing the temperature of the fiber and storing the fiber at the reduced temperature before the step of pumping the fiber; and wherein the method allows the hydrogen and the deuterium to become bound to the core material and the cladding material.
Claims19
An optical system configured for generating a supercontinuum, said optical system comprising:
- a microstructured optical fiber comprising a core and a cladding, said core and/or said cladding comprising hydrogen and/or deuterium;
- and
- a pulsed pump light source configured to feed said optical fiber with light pulses having a peak power density within said optical fiber equal to or higher than 10 W/μm2;
- where the hydrogen and/or deuterium comprised in said core and/or cladding eliminates or reduces degradation of the optical fiber otherwise caused by said light pulses when said light pulses propagate through the optical fiber.
