Abstract

A phase-space description of the Laguerre–Gaussian modes is presented that points out the connection between these modes and the Hermite–Gaussian modes. We exploit the underlying phase-space symmetries to derive a closed-form expression for the Wigner distribution function of Laguerre–Gaussian modes. This expression is as compact as the one for the Hermite–Gaussian modes.
