  Effects of non-ideal optical components in realizing quantum Zeno effect in
an all-optical setup are analyzed. Beam splitters are the important components
in this experimental configuration. Nonuniform transmission coefficient, photon
absorption and thermal noise are considered. Numerical simulation of the
experiment is performed using the Monte Carlo wavefunction method. It is argued
that there is an optimal number of beam splitters to be used for maximizing the
expected output in the experiment.
