2015 (English)In: 24th International Conference on Optical Fibre Sensors / [ed] Hypolito José Kalinowski, José Luís Fabris, Wojtek J. Bock, 2015, Vol. 9634, article id 96343DConference paper, Published paper (Refereed)
Abstract [en]

An optical fiber component and setup were developed to insert and remove gases from hollow-core optical fibers, allowing gas/light mixing over the length of the fiber for gas sensing applications. Transmitted signals acquired at the output of the fiber contain information regarding absorption occurring inside the fiber, providing a spectroscopic signature of the gas or gases in the fiber. Spectra for 1 atm of acetylene (C2H2) around 1525 nm and 1 atm of carbon dioxide (CO2) around 1432 nm were obtained and compared to HITRAN data, showing good agreement. The setup can also be used to prepare gas cells.
