Intensity-induced stopband bending in periodic nonlinear multilayers

A simple and physically appealing theory is developed to describe the intensity-induced "bending" of the stopband region of nonlinear multilayered devices. The theory is subsequently used to graphically map the general response of devices as a function of input intensity and phase detuning. Deeper insight into conventional (known) phenomena is obtained, while new phenomena are revealed, such as "hard" optical limiting, intensity discrimination, and a new arrangement for bistability.<
