The excited circular states are introduced by repeated application of photon creation operator on the circular states. The sub-Poissonian distribution and squeezing effect are discussed. The results indicate that photon creation operator can enhance sub-Poissonian distribution but supress squeezing effects. The Wigner function is studied,which obviously displays its nonclassical feature. The results obtained using the numerical method indicate that the interference effects change alterantly when the exited number m takes odd and even number respectively.
