In this paper, we introduce even and odd deformed photon added nonlinear coherent states which in a special case lead to the even and odd photon-added coherent states |z,m±. After choosing a particular nonlinearity function corresponding to the P¨oschl-Teller potential, we show that they satisfy the over-completeness relation and thus are coherent states in actual concept. Meanwhile, by investigating their non-classical features, we find that in the superposing process the quadrature squeezing disappears. Based on the interaction of a trapped ion with traveling wave light fields, we give a scheme for how to prepare even and odd deformed excited nonlinear coherent states. Finally, we compare their non-classicality aspects with |z,m±.
