Abstract :
Quantum phase parameters have been studied in Multi-wave mixing using Barnett-Pegg formalism. It is shown that reduction of Carruther and Nieto symmetric quantum phase fluctuation parameter U with respect to its coherent state value corresponds to an antibunched state and thus phase fluctuation parameter can be used as a measure of nonclassicality of a state. Further we have compared the measured values of Carruther and Nieto quantum phase parameters U, Q and S and found the reduction of U in five waves mixing optical process directly relates to antibunching.
