This work demonstrated an all-silica photonic bandgap (PBG) fiber capable of low-loss transmission in the mid-infrared region and its application to methane sensing using an alternative method, based on Fourier transform infrared (FTIR) spectroscopy. The spectral measurement and processing were performed using a FTIR spectrometer consisting of a scanning Michelson interferometer.
