PURPOSE:To reduce the number of assembling processes sharply by forming an optical integrated circuit provided with optical elements, an optical guide guiding light to the optical elements and an electrode on one surface and a substrate forming a V groove for mounting optical fibers and an electrode. CONSTITUTION:The optical integrated circuit OIC forms the optical guide OG and light emitting and photodetecting elements (not shown in the drawing) photocoupled with the optical guide and the electrode on one surface of a GaAs substrate or the like and is arranged so that these light emitting and photodetecting elements are opposed to the recessed part S11 of the silicon substrate SI and both of the electrodes contact. On the other hand, the optical guide OG is opposed to the V groove VG and the optical fiber F is arranged on the V groove VG. The electrodes are connected by pressing the electrode on the optical integrated circuit OIC to that on the silicon substrate SI and irradiating light such as CO2 laser to the electrodes to solder them. Said constitution makes it possible to reduce the manhour of assembling processes sharply. |
