TPA-induced long-period gratings in a photonic crystal fiber: inscription and temperature sensing properties

TPA-induced long-period gratings in a photonic crystal fiber: inscription and temperature sensing properties
TPA-induced long-period gratings in a photonic crystal fiber: inscription and temperature sensing properties
We report on the photochemical recording of long-period fiber gratings (LPFGs) in a photonic crystal fiber made of pure fused silica. Such inscription is based on two-photon absorption (TPA) of high-intensity (~300GW/cm) 264 nm 220 fs pulses and brings about LPFGs of high strength and narrow peak width. The characteristic fluence value for the inscription is 1 order of magnitude less than that for a standard telecom fiber irradiated under similar conditions. The temperature sensitivity of TPA-induced LPFGs is ~300 pm/ °C and overcomes that of LPFGs inscribed by other nonphotochemical methods by 2 orders of magnitude.

Abstract

We report on the photochemical recording of long-period fiber gratings (LPFGs) in a photonic crystal fiber made of pure fused silica. Such inscription is based on two-photon absorption (TPA) of high-intensity (~300GW/cm) 264 nm 220 fs pulses and brings about LPFGs of high strength and narrow peak width. The characteristic fluence value for the inscription is 1 order of magnitude less than that for a standard telecom fiber irradiated under similar conditions. The temperature sensitivity of TPA-induced LPFGs is ~300 pm/ °C and overcomes that of LPFGs inscribed by other nonphotochemical methods by 2 orders of magnitude.
