Wideband dynamic range improvement of microwave photonic links

Wideband (4-12 GHz) distortion improvement of a Mach-Zehnder fiber optic link using predistortion linearization is demonstrated. 30 dB IMD/sub 3/ improvement, corresponding to an overall 7.9 dB improvement in SFDR/sub 3/ at 8 GHz is shown.
