Abstract
An optical communication module for optical signal transmission having a structure adopting folding at a filter and a process for producing the same is disclosed. An optical waveguide is formed as a straight waveguide for send/receive of an optical signal. A groove is formed on the optical waveguide substrate. The groove is preferably a V groove positioned diagonally to the axial center line of the substrate. The V groove is disposed in the same direction as an optical waveguide. The above construction can realize an optical send/receive module, which can eliminate the need to provide a bent waveguide, enables all waveguides to be constructed by a straight waveguide, has a small size, and can realize mass production at low cost.
