\section{Theory}  In the following sections a brief theoretical explanation of the operation of the Mach-Zehnder interferometers are given in terms of their gain spectrum response.  \subsection{Mach-Zehnder Interferometer basic operation}  Mach-Zehnder interferometers can be built with bulk optic elements, optical fibers with fiber couplers and using integrated optics. In this course we are going to build MZI interferometers using SOI integrated technology.  \begin{center}  $I_{0}=\frac{I_{i}}{4}\left|\exp\left(-j\beta_{1}L_{1}-\frac{\alpha_{1}}{2}L_{1}\right)+\exp\left(-j\beta_{2}L_{2}-\frac{\alpha_{2}}{2}L_{2}\right)\right|^{2}$  \end{center}
