Abstract
Optical filters in, for example, a wavelength division multiplexing (WDM) fiber optic system or an optical waveguide device are utilized and provided. The optical waveguide device comprises a lower substrate layer, an insulating dielectric layer and a waveguide ribs layer. The insulating dielectric layer, having a first refractive index, is positioned above the lower substrate layer. The waveguide ribs layer, having a second different refractive index, is positioned above the dielectric layer. An optical waveguide is formed from the waveguide ribs layer for transmission of light. In the waveguide ribs layer, an optical filter structure formed, wherein the optical filter structure is integrated onto the same substrate as the optical waveguide.
