Abstract
Low-loss hollow waveguides with multiple dielectric layer are designed and fabricated for use in cavity ring-down spectroscopy. The waveguides are composed of four glass strips with dielectric multilayer that are deposited on the surface in advance. Experimental results show that the waveguides with double dielectric layers have lower losses at a target wavelength in the infrared than those with a single dielectric layer.
