Abstract

In the fields of fibre-optic communication, LiDAR, gas sensing and biomedical imaging, temperature fluctuations affect the wavelength and output power of Vertical-Cavity Surface-Emitting Lasers (VCSELs), thereby reducing system stability and measurement accuracy. This study proposes a VCSEL temperature control system based on the ZYNQ platform (Zynq-7000 All Programmable SoC), aimed at achieving high precision and stability in temperature management. The system integrates a Thermoelectric Cooler (TEC) and a Negative Temperature Coefficient thermistor (NTC), utilizing ZYNQ’s reconfigurable logic and processing units for temperature monitoring and control. A Proportional-Integral-Derivative (PID) control algorithm is implemented for real-time temperature adjustment. Compared with traditional temperature control schemes, this system offers significant advantages in hardware integration and control flexibility. Experimental results show that the ZYNQ-based temperature control system excels in temperature stability and control precision, effectively mitigating the impact of temperature drift on VCSEL performance.
