摘要:
The invention relates to a photonic crystal fiber, in particular single-mode fiber, for the transmission of electromagnetic radiation in the IR wavelength range of >1 μm, in particular in the wavelength range from 1 μm to 20 μm, preferably from 9 μm to 12 μm, having a light-conducting hollow core, in particular a hollow core having a diameter D, and a plurality of hollow bodies, in particular hollow tubes composed of a chalcogenide glass, arranged around the light-conducting hollow core. The hollow bodies (10, 20) are arranged in such a way that the diameter D of the light-conducting hollow core is greater than the shortest wavelength to be transmitted, preferably at least 20 μm, preferably at least 50 μm, particularly preferably at least 100 μm, preferably in the range from 100 μm to 500 μm, in particular in the range from 150 μm to 350 μm, and the damping for the transmission of electromagnetic radiation is
