Among few existing applications of Microstructured Optical Fibers, a new device for measurement of low gas concentration was designed. Developed set-up based on a Photonic Bandgap Fiber (PBGF), which was used as a gas cell. Proposed technique allowed reducing gas sample volume to 0.01 cc. The gas flow inside core of fiber was simulated and result was confirmed experimentally. During the experimental work several types of fibers of various parameters were specially designed, produced and used. Core diameters ranged from 10.9 μm to 700 μm. Various cutting techniques for fibers were investigated.
