PURPOSE:To make the titled device compact remarkably, and to improve the cooling efficiency by coupling >=2 substrates electrically or optically and installing them vertically, and connecting each element and each vertical substrate, or these element and an external apparatus by a metallic coat fiber. CONSTITUTION:Substrates 13a-c formed by combining suitably an optical active element, an optical passive element, and also one or more of necessary electronic circuits are installed vertically at a suitable interval on a substrate 11. The vertical substrates 13a-c and the substrate 11 are connected electrically and/or optically as necessary in order to couple each element. Accordingly, when a desired electric conduction is executed to a flat cable 15 which has been connected through a connector 14, a coupled optical element or electronic element of the vertical substrates 13a-c is driven through an electronic circuit 12. |
