Abstract:
We describe long-period grating inscription in hydrogenated telecom fibers by use of high-intensity femtosecond 352 nm laser pulses. We show that this technique allows us to fabricate high-quality 30 dB gratings of 300 microm period and 2 cm length by use of a three-photon absorption mechanism.
