We consider a laser that is incident normally upon a planar waveguide with a Kerr nonlinearity. In a previous paper [ J. Opt. Soc. Am. 8, 786 ( 1991)] we demonstrated that the waveguide fields can participate in a transverse instability of the incident beam. We examine the evolution of this instability, show that the system evolves to a steady-state pattern, and develop a general instability criterion.
