Abstract

Theoretical predictions and experimental measurements of the transmission characteristics of a 1.0 mm I.D. hollow core silica waveguide have been made as a function of wavelength across the 9-11 μm waveband. Good qualitative agreement is observed between the theoretical and experimental data. Significantly lower attenuation coefficients are attained at the lower end of the waveband as a result of dramatic changes in the complex refractive index of silica brought about by dispersion phenomena associated with a strong absorption band centered at = 9.25 μm.
