Abstract
It is well known that a single-mode Geld is self-phase modulated as it passes through a nonlinear medium exhibiting the Kerr effect. Such a medium can either be a nonlinear crystal or a single-mode fiber. Self-phase modulation received attention from the squeezed-state generation point of view because the detection statistics of a self-phase modulated field are squeezed.1 However, to the best of our knowledge, no similar result appeared concerning multimode fields. In this paper we give a general method for calculating the joint probability density function governing the detection statistics of a multimode self-phase-modulated field.
