Optical module, including a prism covered by a housing

摘要

Provided are an optical module, an optical communication apparatus, and an information processing system including the same. The optical module includes a lower clad layer, an optical waveguide extended in one direction on the lower clad layer, an optical device on the optical waveguide, a prism disposed between the optical device and the optical waveguide and having a higher refractive index than the optical waveguide, a housing covering the prism and the optical device, and an electrode layer adjacent to the prism and disposed between the housing and the optical waveguide.
