  • Method and apparatus for controlling the temperature of a laser module in fiber optic transmissions
    Patent number: 6724791
    Abstract: A semiconductor laser diode for transmitting optical signals in a telecommunications network is housed within a module supported adjacent to a thermoelectric cooling element that is mounted in thermally conductive contact with a heat sink. The cooling element is positioned externally on the surface of the module. The adjacent surface areas of the module and the cooling element are brought into thermal conductivity by a thermally conductive filler occupying the space between the module and the cooling element. The filler conforms to the configuration of the adjacent surfaces of the module and the cooling element to increase the thermal conductivity therebetween for maximum efficiency in the transfer of heat from the laser diode through the module to the cooling element and the heat sink.
