STRUCTURE AND METHOD OF MOUNTING OPTICAL MODULE

摘要

PURPOSE: To provide a structure and a method that enable an optical module to be easily mounted without alignment. CONSTITUTION: A surface light-receiving and emitting type optical element 11 is mounted on a substrate 13, on which a fiber array 18 with a guide hole connectable to a guide pin-attached optical connector is mounted through a spacer. The light receiving part (receiving/emitting part) 12 of the optical element 11 and the fiber 22 end face of the fiber array 18, which are opposite to each other, are aligned through a picture recognizing system. There is no need of installing a high-precision marker on the substrate 13 as conventionally done. High precision for mounting is needed only for one process of mounting the fiber array 18.
