A miniature extrinsic Fabry-Pérot interferometer (EFPI) sensor based on photonic crystal fiber with very low temperature sensitivity is fused by using a simple welding method, which can effectively reduce the cross sensitivity between strain and temperature. And the transmission loss of the HCPCF is very low that allows the cavity length to be as long as several centimeters with good visibility. That makes the sensors may find its application in quasi-distributed sensing.
