V. FIGURES OF MERIT
MWP signal processors can be considered as filtered MWP
links and thus their performance evaluated in terms of three
common metrics, RF gain, noise figure, and dynamic range [79].
Models have been developed recently for filtered MWP links
subject to frequency [80] and amplitude/phase modulation [81].
In [81], the concept of filtered MWP Links is proposed in order
to provide the most general and versatile description of complex
MWP systems. In particular, a field propagation model is developed
where a global optical filter, characterized by its optical
transfer function, as shown in Fig. 1, embraces all the intermediate
optical components in a linear link and a nonmonochromatic
light source characterized by an arbitrary spectral distribution
is considered. Closed expressions leading to the computation
of the main figures of merit concerning the link gain,
noise, and spurious free dynamic range due to intermodulation
distortion are given which are useful as they directly provide
performance criteria results for any kind of processor just by
substituting in the overall closed-form formulas the numerical
or measured optical transfer function characterizing the link.
Successful testing of the model has been experimentally reported
for sliced broadband source and Mach–Zehnder (MZ)
interferometer continuously sampled filters [82].
