文摘This paper reports on the writing of long period gratings （LPGs） in a six-ring pure silica solid core, and large mode area photonic crystal fiber （fiber core diameter p = 10.1 μm） using a CO2 laser system, and the characterization of their strain and temperature sensitivities. Temperature and strain sensitivities in the order of-19.6pm/℃ and -88 pm/με, respectively, were obtained, which were comparable or surpassed values of the similar photonic crystal fiber （PCF）-based LPG or sensor configurations found in the literature.
