SMALL-FORMED OPTICAL MODULE

摘要

An optical module (100) including a protrusion (120) with a designated shape formed on one of the bottom surface of a substrate (101) and the bottom surface of a cavity of a package (115) and the substrate (101) is achieved by matching the protrusion (120) with the depression (106) without operating the luminous element (103) or the light receiving element (104). The optical module of the present invention is manufactured after the passive alignment of the package and the substrate, thereby simplifying the manufacturing process and shortening the alignment time.
