Abstract: A temperature control system is provided for efficiently controlling the temperature of an optical transmitter such as a laser diode. The temperature control system of the present invention reduces power consumption and achieves a higher efficiency by employing a voltage controller and a high-efficiency DC-DC step-down converter between the TEC controller, which drives the thermoelectric cooler, and the microcontroller, which governs the optical transmitter operation. The voltage controller converts an analog voltage command signal into a current-based command signal, which is then sent to the DC-DC step-down converter. The DC-DC converter produces a stepped-down voltage which it supplies to the TEC controller. The TEC controller receives the stepped-down voltage input from the DC-DC converter and outputs a corresponding current signal to the thermoelectric cooler.
