<p><P>PROBLEM TO BE SOLVED: To provide an integrated optical waveguide device with lower propagation loss while maintaining integration and improving compactness, even in the integrated optical waveguide device generating an optical beam having asymmetric intensity distribution. <P>SOLUTION: The integrated optical waveguide device is provided with a substrate 30 consisting of a material having electro-optic effect, an optical waveguide 31 formed on the top side of the substrate, and an optical waveguide 32 formed on the bottom side of the substrate. On at least one end face of the substrate, the optical waveguides formed on the different sides are provided with an emission port 33 and an incidence port 34, respectively. A GRIN lens 10 is arranged adjacently to the one end face so that light emitted from the emission port enters the incidence port. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
