Abstract
In order to solve the practical problem between fast speed of optical switch and slow speed of drive control circuit , a design method of driving and controlling circuit for large-scale optical switch array was presented. High level or low level amplitude of the drive and control circuit could be arbitrarily adjusted by using FPGA to control the digital to analog converter and high-speed switch, which was creative. The new design principle of large-scale optical switch array drive control circuit was introduced completely through the combination of overall design, circuit design and software design. Finally, the test showed that the switching speed of the control circuit was less than 2 ns.
