Paper Abstract

The Hermitian optical phase operator realises Dirac's conception of a phase, conjugate to the photon number for a mode of the electromagnetic field. However, much confusion has resulted from the failure to recognise that the single word "phase" is used to describe distinct concepts in the description of a quantised electromagnetic field mode. We compare and contrast these distinct phase concepts.
