摘要：

We have measured the optical transmission of quasiperiodic dielectric multilayer stacks of SiO2 (A) and TiO2 (B) thin films which are ordered according to a Fibonacci sequence S(j+1) = {S(j-1), S(j)}, with S0 = {B} and S1 = {A} up to the sequence S9 which consists of 55 layers. We observe a scaling of the transmission coefficient with increasing Fibonacci sequences at quarter-wavelength optical thicknesses. This behavior is in good agreement with theory and can be considered as experimental evidence for the localization of the light waves. The persistence of strong suppression of the transmission (gaps) in the presence of variations in the refractive indices among the layers is surprising.
