| Title: | Hollow-core fiber-based high finesse resonating cavity for high sensitivity gas detection | Authors: | Tan, YZ Jin, W Yang, F Qi, Y Zhang, CZ Lin, YC Ho, HL |
Issue Date: | 15-Jul-2017 | Source: | Journal of lightwave technology, 15 July 2017, v. 35, no. 14, p. 2887-2893 | Abstract: | High finesse hollow-core photonic bandgap fiber (HC-PBF) resonating Fabry-Perot gas cells are presented. These gas cells are made with a piece of HC-PBF sandwiched by two single mode fibers with mirrored ends. A HC-PBF cavity made with 6.75-cm-long HC-1550-06 fiber achieved a cavity finesse of 128, corresponding to an effective optical path length of similar to 5.5 m. Experiment with a 9.4-cm-long Fabry-Perot gas cell with a finesse of 68 demonstrated a detection limit of 7 ppm acetylene. Compared with a single-path nonresonating HC-PBF, the use of a high finesse resonating HC-PBF cavity can reduce significantly the effect of modal interference on gas detection and improve the detection sensitivity. The cavity-enhanced HC-PBF gas cells enable stronger light-gas interaction and can be used to develop all-fiber gas sensors with high sensitivity and fast response. | Keywords: | Fabry-Perot resonator Gas sensor Optical fiber sensor Photonic crystal fiber |
