A new technique for fabricating a photonic bandgap fiber is proposed. A multilayer Si-SiO2 film is deposited upon a silica glass fiber, and a clear bandgap is observed in the loss spectrum. The properties of the bandgap are easily controlled by adjustment of the thickness and the refractive index of the multilayer film.
