Abstract: | A drive system for a 16-channel waveguide optical phased array beam deflector is presented, where the control unit for drive voltage regulation is implemented with a field programmable gate array (FPGA) chip. With the drive system, a beam scan rate above 580 kHz can be achieved, which is far higher than that obtained with other implementation methods based on microcontrollers. |
