Temporal pulse response of quasi-periodic Fibonacci Fabry-Perot type optical filters

A specific behaviour of quasi-periodic multilayers is the existence of isolated peaks inside the forbidden transmission gap. Thus, quasi-periodic multilayers may be an alternative to the periodic structures with defects. The compressing capacity of quasi-periodic Cantor filters has been presented by other authors. We analyse comparatively the compressing capacity of quasi-periodic Fibonacci (F) and Fibonacci Fabry-Perot (FFP) multilayers at normal incidence. Various pairs of nondispersive layer refractive indices and different embedding media are considered. Symmetrical FFP multilayers admit wider ranges of layer refractive indices at which parameters characterising the compressing capacity attain certain levels
