We report for the first time a laser microfabrication and its characteristics of photonic crystal structure in vitreous silica. It is two-dimensional triangle lattices composed of hollow cylinders with a periodicity of approximately 1.2 μm. Infrared spectroscopic measurements revealed dielectric-periodicity-matched transmission valleys centering approximately at 4100 cm-1 for H-polarization and 4000 cm-1 for E-polarization, respectively.
