  • Publication number: 20220094138
    Abstract: A structure and a manufacturing method of an optical transmission module, in which output light of each of a first optical transmission unit and a second optical transmission unit is combined into one and transmitted through an optical fiber. In order to manufacture the optical transmission module, the first optical transmission unit and the second optical transmission unit are separately manufactured using a wafer-level packaging process and then are stacked. As a result, emission of generated heat is divided into a first heat sink installed in the first optical transmission unit and a second heat sink installed in the second optical transmission unit so that better heat dissipation efficiency is achieved than a conventional optical transmission module. In addition, a mounting area may also be reduced to ½ of the conventional module.
