PURPOSE:To arbitrarily and freely integrate a large quantity of optical elements and to reduce in size in terms of its high integration by stereoscopically associating boards such as a photoelectric integrated circuit board or an optically integrated circuit board, an optical waveguide board and an electric circuit board. CONSTITUTION:A photodetector 13 and a laser 14 of a photoelectric integrated circuit board 1 are respectively optically connected to the waveguides 20 of optical waveguide boards 2. Of course, the boards 1 are similarly electrically connected to boards 3. In the connection, particularly in the case of optical connection, precise aligning is required, but positioning guide pins, other guide, etc., are provided between corresponding boards to be aligned. In the optical connection, it is necessary to obtain an accuracy of about 1mum by the guide pin and the guide. In concrete connections, in the case of electric connection, corresponding conductors may be merely abutted against or brought into contact, but in the case of optical connection, various methods are considered. |
