In this paper, an octave-bandwidth microwave photonic link with a third-order limited spurious-free dynamic range of 121 dB in a 1-Hz bandwidth has been demonstrated.Abstract:
An octave-bandwidth microwave photonic link with a third-order limited spurious-free dynamic range of 121 dB in a 1-Hz bandwidth has been demonstrated. The link noise figure of 9 dB at a modulation frequency of 2 GHz was achieved by using a bias-shifted Mach-Zehnder modulator with an optical input power of 500 mW. This level of performance was realized without electronic or optical linearizationread more

Optical carrier filtering for high dynamic range fibre optic links
TL;DR: In this article, an external carrier filter is used with an externally modulated fiber optic link to maintain high dynamic range operation with significantly reduced optical power levels, achieving a spur-free dynamic range of 115 dBHz/sup 2/3/ with a received optical power of only 1.5 mA.
