Abstract:	A long-period fiber-grating sensor with a high strain sensitivity of −7.6 pm/με and a low temperature sensitivity of 3.91 pm/°C is fabricated by use of focused CO₂ laser beam to carve periodic grooves on a large- mode-area photonic crystal fiber. Such a strain sensor can effectively reduce the cross-sensitivity between strain and temperature, and the temperature-induced strain error obtained is only 0.5 με/°C without using temperature compensation.
