Abstract
The invention intends to provides an optical waveguide device having a structure that satisfies the low drive voltage characteristic and the low propagation loss characteristic at the same time. The optical waveguide device contains a conductive or semiconductive lower electrode, an epitaxial or single orientational buffer layer provided on the lower electrode, an epitaxial or single orientational optical waveguide provided on the buffer layer, and an upper electrode of a conductive thin film or a semiconductive thin film, provided on the optical waveguide. The optical waveguide device is able to modulate, switch, or deflect incident light beams guided into the optical waveguide by applying a voltage between the upper electrode and the lower electrode.
