a Microwave-photonic link measurements; RF output power as a function of RF input power, showing the signal the third-order spur. Extrapolated linear trends and the third-order intercept point are shown for reference. b RF link gain as a function of optical power in the ‘emit’ waveguide. The measurements were performed using two different PPER devices, with active lengths of L = 17 mm (blue) and L = 1.5 mm (red). c Corresponding noise figure and d third-order spur-free dynamic range. The intermodulation SFDR3 is 3.2 dB Hz2/3 lower than the results shown here, which were measured using the third harmonic.
