Abstract

The operation principle of scanning DBR laser was introduced and its multi-channel driving parameters was summarized. Based on FPGA, a multi-channel high-speed and high-precision current drive circuit was designed and fabricated, a scanning laser tuning characteristic testing system was integrated, and parameter control and testing programs were designed to achieve automatic testing. Experimental tests have proven that the developed testing system can well meet the testing requirements of scanning lasers, with a simple structure, high accuracy, and fast speed.
