摘要： PROBLEM TO BE SOLVED: To provide an optical waveguide device whose loss is made low, which has both of facility and reproducibility in manufacture and which has an inflection point. SOLUTION: The basic structure of an optical waveguide holding the core of optical communication technology is obtained by connecting a straight line and a curved line or connecting a curved line and a curved line, and includes the inflection point. By providing axial deviation to the inflection point in order to reduce light loss at the inflection point and forming a gap between the end faces of both waveguides at the connection part where the axial deviation is provided, the low-loss and high-quality optical waveguide device is manufactured with good reproducibility as designed.

摘要： PROBLEM TO BE SOLVED: To provide a method for manufacturing a polyimide optical waveguide which has a sufficient flatness and a small optical loss without bringing about a deformation for remarkably impairing a quality of a product such as a warpage, a waviness, a recess, a protrusion or the like. SOLUTION: The method for manufacturing the polyimide optical waveguide comprises the steps of forming a polymer layer by coating a fluorinated polyimide solution or a fluorinated polyamide acid solution on a fluorinated polyimide board, drying and heating the solution so that as a support of the polyimide board, a flat support having a higher heat resistance than a heating temperature and a size larger than that of the polyimide board is used, heating the solution at a higher heating temperature than a glass transition temperature of the polyimide board, and holding the solution until the entire surface of the polyimide board is brought into contact with the surface of the support.
