Abstract: The present invention relates to an optical waveguide and method of manufacturing the same. An optical waveguide is constructed using a clad layer having a refractive index almost same to a core layer in an input/output region coupled to an optical fiber. The optical waveguide is constructed using the clad layer having a large difference in the refractive index with the core layer in an active region having an electrode. Therefore, a driving voltage, a driving power and a coupling loss are reduced to improve a characteristic of the optical waveguide device.
