摘要：
The elliptically polarized nonlinear beam propagation in a two-dimensional optical guided-wave system that contains isotropic Kerr media is solved numerically by using the finite-element method. Computed results for the nonlinear substrate exhibit novel transverse effects, such as spatial modulational insta.bilities for solitons emitted from the film. Since soliton emission can be interpreted in terms of self-induced Cerenkov radiation, these instabilities can be classified as Cerenkov instabilities. The sensitivity of the beam propagation to the initial state of polarization suggests the possibility of constructing new photonic devices. © 1990 Optical Society of America.
