PBG Fiber Low Concentration Gas Sensor
The photonic bandgap fiber for a high-sensitivity, compact set-up, which enables the precise measurement of low concentration of gas was designed. Fiber was used instead the traditional glass gas cell during the spectroscopic measurements. Ar ion beam was proposed among the other methods to process the inlet and outlet surface of fiber and adjust it to the required parameters. The gas flow inside PBF fiber and its optical properties were investigated.
