Abstract: Solutions of coupled-mode equations describing intensity-induced Bragg coupling of counterpropagating modes in a nonlinear distributed-feedback structure may become spatially unstable. Instability leads to nonpassing plateaus in the intensity transmission characteristics. This induces strong optical limiting action in the transmission mode and lower thresholding in the reflection mode.
