For this purpose, these two states as the two input modes are injected into a Mach-Zehnder interferometer and Wigner function of the output state is studied. Finally, the presented formalism is applied to two known nonlinear coherent states. The results show that output field has non-classical property LA eng UL http://opsi.ir/article-1-1220-en.html M3 ER -
