Abstract:
Examples of systems and methods for integrated photonic broadband microwave transceivers are disclosed based on integrated coherent dual optical frequency combs. In some cases, when the system is configured as a transmitter, multiple radio frequency (RF) carriers can be generated, which can either be encoded independently, or used for broadcasting the same information into different bands. In some cases, when the system is configured as a receiver, the spectrum of the input signal can be sliced into several spectral segments for low-bandwidth detection and analysis. In some systems, the optics-related functionalities can be achieved via integrated optic technology, for example based on silicon photonics, providing tremendous possibilities for mass-production with significantly reduced system footprint.

Claim (Index 28):
A microwave photonics system configured as a short-burst microwave signal analyzer, the microwave photonics system comprising:\n a continuous-wave laser source; a dual-comb generator configured to convert output of the continuous-wave laser source to two optical frequency combs (OFC 1  and OFC 2 ) with slightly detuned comb spacings; a broadband electro-optic modulator (EOM) located downstream of said OFC 1  to modulate an input radio frequency (RF) signal into the optical domain as the sidebands of comb lines of said OFC 1 ; an optical storage/frequency shifter located downstream of said EOM; a first wavelength division multiplexing (WDM 1 ) system configured to receive an optical input directly traceable to an output of said OFC 1  and to provide a first set of wavelength channels; a second wavelength division multiplexing (WDM 2 ) system configured to receive an optical input directly traceable to an output of said OFC 2  and to provide a second set of wavelength channels; a set of I/Q detectors each configured to receive as a first input a first wavelength channel of said first set of wavelength channels from WDM 1  and as a second input a second wavelength channel from said second set of wavelength channels from WDM 2 , said first wavelength channel and said second wavelength channel having substantially the same frequency coverage; and a digital signal processor configured to receive outputs from said set of I/Q detectors and to produce an output representative of at least an amplitude or a phase of said input RF signal.
