Abstract

The output power and wavelength of semiconductor lasers are mainly affected by operating temperature. In order to improve the stability of Laser Diode (LD), a temperature control system is designed in this paper. This system adopts an advanced Particle Swarm Optimization (PSO) algorithm to resolve real-time Proportional-Integral-Derivative (PID) parameters for different input, which is implemented on field-programmable gate arrays (FPGA) with excellent parallel performance. Experimental results show that the LD can stabilize with temperature stability of 0.20% within 1 hour of operation, output optical power stability of 0.05%, and the deviation of optical wavelength 0.03𝑛𝑚.
