| 英文摘要 | The present invention relates to an apparatus for controlling temperature of an optical module using an uncooled laser diode. A first setup unit for establishing low-temperature setup voltage and a second setup unit for establishing high-temperature setup voltage determine first and second threshold voltages suitable for low-temperature and high-temperature setup voltages, respectively. First and second comparators compare the low-temperature and high-temperature setup voltages with sensor voltage received from a sensor voltage entry unit, respectively. The output signals of the comparators are applied to a logic circuit, such that the logic circuit generates on/off signals according to the result of the comparison. The logic circuit generates a high-level signal only when the sensor voltage escaped from a predetermined voltage range, and thus operates the temperature control circuit. Therefore, the TEC and the heater contained in the TEC/heater mounting member are operated to generate heat, such that the uncooled laser diode can be heated or cooled at only predetermined temperature. As a result, the uncooled laser diode can be heated or cooled at only predetermined temperature, controls temperature of the optical module at a low power level, resulting in reduction of power consumption. |
