Abstract:
1. An optical device module comprising: a substrate; an interlayer insulating silicon oxide (SiO an optical waveguide including silicon nitride (Si an optical device including a vertical cavity surface emitting laser (VCSEL) or a photodiode and disposed over the optical waveguide; a prism disposed between the optical device and the optical waveguide; and a buffer layer disposed between the prism and the optical waveguide, wherein the prism has a wedge-shape having an incline plane with respect to an extending direction of the optical waveguide and includes gallium phosphide, and wherein the incline plane of the prism has an inclination angle of about 35.2 degrees with respect to the extending direction of the optical waveguide to have the maximum coupling efficiency of the optical device module.
