摘要：
Infrared gas sensors employing hollow-core photonic crystal fibers are reported. A hollow-core photonic crystal fiber in the gas cell of the sensor was inserted between a single mode fiber and a multi-mode fiber in the light path. The gaps between the facets of hollow-core photonic crystal fiber and single mode fiber were optimized to increase the coupling efficiency. The gas chambers were modified to reduce the time for filling. Broadband and laser sources were employed to determine acetylene at concentrations between 0% and 0.6%. The resolution was 0.084ppm and the stability was 0.556%. These sensors have promising applications for trace gas measurements.
