By using the definition of Wigner function in Fock states representationWigner functions for the photon_added and photon_depleted even and odd coherent states is reconstvucted. The results show that photon_added even and odd coherent stat es always demonstrate non_classical characteristics but photon_depleted even and odd coherent states demonstrate non_classical characteristics only when k t ake odd and even number respectively.
