abstract = "This paper describes the behavior of a microwave external
modulation link composed of: optical and radio frequency sources,
Mach-Zehnder modulator (MZ), optical fiber and photodetector. The
electro-optical circuit modulates the RF signals and transmits
them to the detector through the optical fiber. The main
contribution of this paper lies on the different approach to the
system analysis; we consider an off-quadrature biased MZM. By
extending the mathematical model found in the literature for the
case of different bias voltages, we compute a few performance
parameters of the system like Gain and SFDR. For computing those
parameters we use a custom made program written in the MATLAB
environment. In addition to the system's characterization and
insights on its off-quadrature operation, another contribution of
this article is the model validation. We assembled the
electro-optical circuit and measured some performance parameters
for different values of bias voltages. By comparing the
experimental results with the theoretical ones, we validated the
model. Finally, we also consider the applications for microwave
signals distribution by optical fiber links.",
