Abstract
We report on the fully digital implementation of various locking schemes within the frame of microwave photonics systems such as Pound-Drever-Hall (PDH) for ultra-stable lasers based on Fabry-Perot cavities, heterodyne lockin amplifiers for fiber links, laser stabilization of optical clocks. We demonstrate similar performances over their analog counterparts, with a net gain on flexibility and reconfigurability.
