Photonic Processing for Wideband Cancellation and Spectral Discrimination of RF Signals

Figure 3

A time evolving spectral plot (waterfall plot) showing positive and negative sidebands around the central carrier frequency. A 400 MHz signal is common to both modulators whilst a 500 MHz signal is present in only one modulator and is unaffected by phase changes.
