Abstract: The optical transmitter module may include a thermal-electric cooler comprising at least one metal pattern formed on a side of a cooling plate temperature of which is controlled by thermo-electric cooling elements, a laser diode installed in one of the at least one metal pattern, and a monitor photo diode which is installed in another one of the at least one metal pattern and monitors change of light signals emitted from the laser diode. Therefore, since elements are located on the same side of the cooling plate, the optical transmitter module may have a simple structure and an advantage that light signals emitted from the laser diode can be directly coupled to the optical fiber without optical path conversions. Also, since the laser diode is installed with a small gap from thermal-electric elements, the temperature control characteristics of the thermal-electric cooler can be enhanced.

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.
