Abstract
An integrated optic circuit according to the present invention is produced as a hybrid integrated optic circuit using two or more kinds of substrates in which only the portion of high performance and high degree of integration is formed of the substrate of a material of high cost and high performance while the other portion of lower degree of integration is formed of the substrate of a material of low cost. Therefore, in the integrated optic circuit according to the present invention, the distance between the waveguides to be coupled with optical fibers can be larger than the outside diameter of the optical fiber, and the integrated optic circuit according to the present invention can be produced easily at low cost.
