DARPA DODOS develops Optical frequency synthesizers (OFC) chips to enhance LIDAR, coherent communications, and chemical sensing

The need for better radar in World War II drove the development of radio frequency control, and its miniaturization in subsequent decades revolutionized a host of military and consumer applications. The generation of accurate signal frequencies from a single reference oscillator called microwave frequency synthesis, brought about many advanced technologies now critical to the military, such as wireless communications, radar, electronic warfare, atomic sensors and precise timing.
