摘要： An analog circuit including a voltage divider for providing a first voltage corresponding to an actual temperature of said thermal tuning element of the laser; an analog comparator generating an analog output current for comparing the first voltage with a reference voltage, the reference voltage being representative of a temperature of said thermal tuning element of the laser corresponding to a desired wavelength of the laser; and a heating element thermally coupled to said thermal tuning element, wherein the analog comparator increases said analog current to the heating element, when the first voltage is less than the reference voltage; and decreases said analog current to the heating element, when the first voltage is larger than the second reference voltage.
