Abstract
A universal programmable multi-quantum-well (MQW) spatial light modulator (SLM) driving circuit is developed. With a twice scanning, it can generate programmable signals to drive a non-linear MQW SLM by using a software preprocessing unit. By adjusting the switching network of the driving circuit, this circuit can reduce the switching noise and improve the output precision. The chip test results show that the driving voltage can swing from 0 to VDD, and its resolution could be close to 256 with a pixel area of only 65 × 65 μm2.-
