A circuit using the singlechip as key component for temperature control for DFB laser diode is designed in this article. An imbalance electrical bridge for measuring the temperature of laser diode is used in this circuit, and the result of measurement is converted to digital quantity by ADC. After that, the error signal is gotten through the digital PID calculation. At last, the DAC chip make error signal be voltage to drive power amplifier for TEC. The function of set point and display of real time temperature is also added. After the test for a long time, we confirm the precision of temperature is better than ±0.001°C.
