Abstract :
The proposed technique overcomes the dynamic range limitations imposed by the signal-pilot beating in analogue fibre optic links. A spurious free dynamic range improvement of 31.8 dB is demonstrated in an experimental link where a pilot tone is used to control the bias point of a Mach-Zehnder modulator.
