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.
