Abstract:
PROBLEM TO BE SOLVED: To provide a method for forming an optical waveguide by which the optical waveguide having a light reflecting mirror which forms a prescribed inclined angle to the light propagating direction is easily formed by a simple process with excellent reproducibility and a method for manufacturing optical transmitter-receiver. SOLUTION: A forming mold 21 having plural opening parts 21a is arranged on a clad layer 12 formed on a substrate 11. The opening parts 21a of the forming mold 21 are opened in a nearly rectangular parallelepiped shape, and inclined parts 21b, 21c formed so as to incline at a prescribed inclined angle along the light propagating direction are provided at both end parts. After core layer forming material is poured into the opening parts 21a to fill it, core forming material is hardened by irradiating the material with light from the upper side of the substrate 11. Further, the clad layer is formed after the forming mold 21 is removed from the substrate 11. Thus, the light reflecting mirror forming the prescribed inclined angle to the light propagating direction is formed at both end parts of the core layer composing the optical waveguide.
Abstract:
PROBLEM TO BE SOLVED: To provide a manufacturing method of optical waveguide to manufacture easily an optical waveguide capable of keeping a high optical propagation characteristic irrespective of the kinds of supporting base substances. SOLUTION: A dummy layer having a pattern in which a solution, in such as a grating shape can infiltrate sufficiently up to a central part, is formed on a transparent substrate 11, and an optical waveguide 16 is formed thereon. Then, the transparent substrate 11 is immersed into an acidic solution. The dummy layer is dissolved to be removed, an area in which the dummy layer has been formed becomes a gap 17, and a clad layer 13 is brought into a condition contacting with one portion of the substrate 11. A multi-layered wiring board 18 is made thereafter to contact closely with the optical waveguide 16 via an adhesive layer 19 comprising a photo-curable resin, then the layer 19 is irradiated with a beam to be cured, and the writing board 18 is fixed to the optical waveguide 16. Further, physical force F is appied to the transparent substrate 11 to separate the substrate 11 from the optical waveguide 16. The waveguide 16 is thereby transferred to the wiring board 18. Since the waveguide 16 contacts partially with the transparent substrate 11, the substrate 11 is separated easily.
