Hollow SiO_2- and GeO_2-based glass waveguides were fabricated for mid-infrared light transmission. By changing the percentage of Si or Ge atoms in the glass systems, we can control the low-loss wavelength range which appears near the resonance absorption peak. Efficient transmission was demonstrated in the 7-12μm wavelength range by using hollow waveguides made of pure-SiO_2, (SiO_2)_<63>(TiO_2)_<16>(Na_2O)_<21>, and (GeO_2)_<88>(Ta_2O_5)_<10>(K_2O)_<10> glasses. For a CO_2 laser of 10.6μm wavelength, the lowest loss of 1.1 dB/m was attained with the waveguide of 1mm diameter.
