Photonic crystal fiber, manufacturing method thereof, and super continuous light source

摘要

The present invention relates to a photonic crystal fiber (PCF), a method of manufacturing the same, and a super continuous light source including such a PCF. The PCF has a longitudinal axis and includes a core extending along the longitudinal axis and a cladding region surrounding the core. At least the cladding region comprises a plurality of microstructures in the form of a covering, extending at least along the longitudinal axis of the PCF in a microstructured length section. In at least the degradable length section of the microstructured length section, the PCF comprises hydrogen and / or deuterium. At least the in-decomposable length section, the PCF is further comprised of a primary coating surrounding said cladding region, wherein the primary coating is airtight with respect to the hydrogen and / or deuterium at a temperature lower than T _h, T _h Is at least about 50 DEG C, preferably 50 DEG C T _h 250 DEG C.
