Abstract
We predict a new optically nonlinear effect in semiconductors in which a traveling interference pattern generated by two optical waves excites multiple high-field Gunn domains which move phase locked with the interference fringes. The optical waves simultaneously diffract off the refractive index change generated by this oscillating space-charge field.Keywords
