Glogower, refers to the operator where the phase is introduced as an approximate polar decomposition of the creation and annihilation operators. It is defined as and its adjoint Their commutation relation is where | 0 ⟩ is the vacuum state of the harmonic oscillator. They may be regarded as a phase operator because where a † a is the number operator. So the exponential of the phase operator displaces the number operator in
