    Photonic Bandgap (PBG) Fiber was developed for a new gas-sensing device. The micro-capillary gas flow inside fiber and light guiding parameters were estimated in order to develop a high-sensitivity gas concentration measuring system. Darcy - Weisbach equation for non-compressible flow and quasi-Panhandle equation for compressible gas flow were used for the calculation of gas velocity. Core diameters of fibers ranged from 10.9 to 700 μm. The results of numerical simulations were compared with experimental results. Attenuation was calculated and concentrations of ammonia and CO2 were measured.
