Nonlinear multilayer Fabry-Perot resonators as narrowband optical limiters

Multilayer structures which can be considered as one-dimensional photonic crystals are very promising in the context of low-threshold nonlinear optical devices. That generally takes place by the two reasons: local multiple enhancing of optical field in crystal defects and sharp spectral characteristics of such structures. Multilayer Fabry-Perot resonators have been theoretically and experimentally studied as narrowband optical limiters.
