Abstract :
We inscribed long-period gratings in a hydrogenated single-mode fiber (SMF-28) by high-intensity femtosecond near-ultraviolet pulses via a three-photon absorption mechanism. Due to energy deposition in the fiber cladding, such gratings are similar to those fabricated by CO2 laser induced heating, mechanical pressure, or electric arc. We found that these gratings exhibit significant polarization properties.
