| Abstract:This paper discusses the design and implementation of 100G tunable laser optical module based on tunable laser, and make a brief introduction to various modules function in MCU.The main technologies involve the wavelength tuning,wavelength locking,power compensation and TEC control. Through the analysis of the tranditional position PID algorithm,making improvement on it. The improved PID algorithm can avoid the wavelength drift or even lockout due to the adjusting value changing during the wavelength locking process. |
