Abstract

Investigations of the behavior of multilayers made of nonlinear materials have usually been restricted to structures designed for their low-power performances.¹ Fabry-Perot filters, narrow-band mirrors, and Fibonacci filters have been investigated, but in all cases their optical properties are only distorted at high power and do not converge toward any chosen sets of properties. Designing multilayers that meet specific spectral requirements at both low and high powers is more attractive and would open up a tremendous range of applications. A few steps have been made in this direction, and a technique has been devised that leads to linear and nonlinear refractive index profiles. I will present the basic idea behind this technique and illustrate its use. I have designed a filter that exhibits some specific properties at both low and high powers. I will use simulation to illustrate the path followed by the filter's optical properties as it goes from the low-power to the high-power state.
