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 ρ = 10.1 μm) using CO2 laser system, characterization their strain temperature sensitivities. Temperature sensitivities order −19.6 pm/°C −88 pm/μɛ, respectively, were obtained, which comparable or surpassed values similar (PCF)-based LPG sensor configurations found literature.
