In this paper, after a brief review on the nonlinear coherent states and parity operator by using this operator and nonlinear displacement-type operator, we construct new operators which by the action of them on the vacuum state of the field, we generate a superposition of two nonlinear coherent states and two-modes entangled nonlinear coherent states. Also, we show that by the generalization of the presented method in this paper, the superposition of more than two nonlinear coherent states with the vacuum state of the field and n-mode entangled nonlinear coherent states can be generated.

Keywords: Superposition of states, Entanglement, Superposition of nonlinear coherent states, Entangled nonlinear coherent states.
