Transmission properties of hollow waveguides utilizing dielectric multilayer are examined by using a photonic bandgap theory. Theoretical results show that, in the waveguide having quarterwave film stack, a large number of films is necessary to obtain low loss property. It is shown that covering the dielectric films with a metal layer is effective to reduce the number of die electric film. To verify the effect of this design, we fabricate a prototype waveguide with three dielectric layer of SiO2/Ta2O5/SiO2 and a silver cover layer. From the loss spectrum of the waveguide, we confirm that, as designed, the waveguide shows wideband low loss at the wavelength of Nd:YAG laser light 1.06 μm.
