    "abstract": "A clear physical meaning of the Carruthers-Nieto symmetric quantum phase\nfluctuation parameter (U) has been provided in Susskind Glogower and Barnett\nPegg formalism of quantum phase and it is shown that the reduction of phase\nfluctuation parameter U with respect to its coherent state value corresponds to\nan antibunched state. Thus nonclassicality of a state may be manifested through\nthe phase fluctuation parameters. As examples, quantum phase fluctuations in\ndifferent optical processes, such as four wave mixing, six wave mixing and\nsecond harmonic generation have been studied by using Carruthers-Nieto quantum\nphase fluctuation parameters. The operators required for the calculation of\nquantum phase fluctuations are expressed in closed analytical forms (up to\nsecond order in coupling constant). It is also found that the reduction of\nphase fluctuations compared to their initial values are possible in all three\ncases which means nonclassical (antibunched) state exists in all these cases.",
