| Title: | Hollow-core fiber Fabry-Perot photothermal gas sensor | Authors: | Yang, F Tan, Y Jin, W Lin, Y Qi, Y Ho, HL |
Issue Date: | 1-Jul-2016 | Source: | Optics letters, 1 July 2016, v. 41, no. 13, p. 3025-3028 | Abstract: | A highly sensitive, compact, and low-cost trace gas sensor based on photothermal effect in a hollow-core fiber Fabry-Perot interferometer (FPI) is described. The Fabry-Perot sensor is fabricated by splicing a piece of hollow-core photonic bandgap fiber (HC-PBF) to single-mode fiber pigtails at both ends. The absorption of a pump beam in the hollow core results in phase modulation of probe beam, which is detected by the FPI. Experiments with a 2 cm long HC-PBF with femtosecond laser drilled side-holes demonstrated a response time of less than 19 s and noise equivalent concentration (NEC) of 440 parts-per-billion (ppb) using a 1 s lock-in time constant, and the NEC goes down to 117 ppb (2.7 × 10-7 in absorbance) by using 77 s averaging time. | Publisher: | Optical Society of America | Journal: | Optics letters | ISSN: | 0146-9592 | EISSN: | 1539-4794 | DOI: | 10.1364/OL.41.003025 | Rights: | Journal © 2016 Optical Society of America © 2016 Optica Publishing Group.
