摘要

The present invention relates to a photonic crystal fiber (PCF), a manufacturing method thereof, and a supercontinuum light source including such a photonic crystal fiber. The photonic crystal fiber has a longitudinal axis, and includes a core extending along the length of the longitudinal axis and a cladding region surrounding the core. At least, the cladding region includes a plurality of microstructures in the form of inclusions extending along the longitudinal axis of the photonic crystal fiber at least within the microstructured length section. The photonic crystal fiber includes at least one of hydrogen and deuterium at least within the degradation resistant length section of the microstructured length section. The photonic crystal fiber further includes a main coating surrounding the cladding region, at least within a degradation resistant length section, wherein the main coating is hermetic to at least one of hydrogen and deuterium at a temperature below Th. Where Th is at least about 50 ° C., preferably 50 ° C. Th 250 ° C.
