Phase properties of excited coherent states
Ravinder Nath, Satish Kumar Muthu · Quantum and Semiclassical Optics Journal of the European Optical Society Part B · 1996
The phase properties of states generated by excitations on a coherent state have been studied by evaluating the expression for the phase probability distribution, using the recent formalism of Pegg and Barnett in which the existence of a Hermitian optical phase operator has been shown. This distribution has been further used to evaluate the variance of the phase operator and the number - phase uncertainty product.
