Abstract
We inscribed long-period gratings in a hydrogenated SMF-28 fiber by high-intensity femtosecond near-UV pulses via a three-photon absorption mechanism. Due to energy deposition in the fiber cladding, such gratings are similar to those fabricated by C02 laser induced heating, mechanical pressure or electric arc. We found that these gratings exhibit significant polarization properties.
