Abstract
We report to the best of our knowledge for the first time on the fabrication and characterization of CO2-laser written long-period gratings in a large-mode area photonic crystal fiber possessing a core diameter of 25 μm. The gratings have low insertion losses (<1 dB) and high attenuation (>10 dB) at the resonant wavelengths, making them particularly interesting for high power applications.
