Abstract: A system and method for generating optically synthesized microwave signals with broadband tunability is disclosed. The system includes a first laser and a second laser, where the first laser and second laser are optically coupled to each other. The second laser is operable to receive optical signals injected by the first laser, and to output optical signals via one or more feedback paths. The system provides for singular or mutual optical injection. A photodetector is optically coupled to the second laser over the one or more feedback paths, and operable to convert optical signals to electrical signals. A phase modulator is coupled to the photodetector, where the electrical signals from the photodetector are operable to drive the phase modulator and close the one or more feedback paths. The respective lengths of the feedback paths may be selected such that their corresponding lengths provide a frequency spacing for optical signals therein that is significantly smaller than a frequency of microwave signals.

Abstract: An apparatus is provided for RF signal discrimination. A master laser of the apparatus is connected to an optical input of an optical phase modulator. The optical phase modulator is configured to receive a plurality of RF signals at an RF input and further configured to receive an output from the master laser at an optical input. A slave laser operating below a lasing threshold is configured to receive a modulated output from the optical phase modulator. An optical filter is configured to receive a mixed signal generated inside the slave laser. A photodetector receives the filtered mixed signal and is configured to recover a RF signal from the plurality of RF signals, where a frequency of a sideband of the recovered RF signal corresponds to a mode of the slave laser.
