| Abstract: | In order to achieve the intelligent control of DFB laser array,an intelligence,high precision and numerical controlling driver circuit was designed.The system takes MCU and FPGA as the main control chip,and it has the characteristics of compact,high-efficiency,no impact,switching protection etc..The output of the DFB laser array can be determined by an external adjustable signal.The system can transform the analog control model into a digital control model,which improves the performance of the driver.The system can monitor the temperature and current of DFB laser array in real time.The output precision of the current can reach ± 0.1 mA,which ensures the stable and reliable operation of the DFB laser array.This driver can benefit the flexible usage of the DFB laser array. |
