Spatio-temporal instabilities for counterpropagating waves in periodic media.
Nonlinear evolution of coupled forward and backward fields in a multi-layered film is numerically investigated. We examine the role of longitudinal and transverse modulation instabilities in media of finite length with a homogeneous nonlinear susceptibility <font face="Symbol">c</font>((3)). The numerical solution of the nonlinear equations by a beam-propagation method that handles backward waves is described.
