Abstract
ln accordance with a described example, a microwave photonic signal processor (MPSP) is disclosed for processing a first and a second input wavelength-division multiplexing (WDM) signals, each comprising RF sidebands and optical carriers, which comprises a programmable photonic processor (PPP) for individually adjusting the magnitude and phase of each optical carrier and RF sideband of the first WDM signal; an optical combiner for combining the output signal of the PPP with the second WDM signal; and a photodetection stage for converting the signal output by the optical combiner to an electrical signal.
