Abstract

An optical device module includes a substrate, an interlayer insulating layer on the substrate, an optical waveguide on the interlayer insulating layer, an optical device on the optical waveguide, and a prism disposed between the optical device and the optical waveguide. The prism has a refractive index greater than a refractive index of the optical waveguide.
