    New generation of light fibers: Photonic Bandgap fibers (PBG fiber) were applied as gas cells in the concentration measurement sensor. Several types of PBG fibers of various parameters were designed. Core diameters ranged from 10.9 to 26.25 μm. The precise cutting method for the PBG fiber was proposed. Capillary gas flow rate within the fiber was simulated and measured. Attenuation of newly produced fibers was investigated and concentration of ammonia gas was measured using the new type sensing system.
