Abstract
We propose a simple scheme to generate an arbitrary photon-added coherent state of a travelling optical field by using only a set of degenerate parametric amplifiers and single-photon detectors. Particularly, when the single-photon-added coherent state (SPACS) is observed by following, e.g., the novel technique of Zavatta \emph{} (Science 306, 660 (2004)), we also obtain the generalized optical entangled state. Finally, a qualitative analysis of possible losses in our scheme is given.
