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.
Claims22
An apparatus comprising:
- a supercontinuum light source configured for providing high-brightness and/or high-power emission in the visible part of the spectrum;
- the supercontinuum light source comprising a pulsed pump light source and an optical fiber;
- said fiber comprising a core and a cladding comprising a core material and a cladding material, respectively, at least a part of said core comprising silica;
- said pulsed pump light source being arranged to feed said fiber with pulses;
- and
- said core material and/or said cladding material comprising hydrogen and/or deuterium.
