摘要

Strong localization from the Fabry-Perot-like resonances that occur in symmetric Fibonacci superlattices is presented in this study. When compared with traditional Fabry-Perot resonators, in symmetric Fibonacci superlattices, the middle space is a variant rather than an invariant half-wavelength thickness for each resonance with different orders. In addition, the electric fields of the resonances may be located on both sides of the space layer in the superlattice, which is in contrast to those in a traditional Fabry-Perot resonator. The electric field of the resonances is strongly localized as the generation order increases. Moreover, the group delays of these peaks increase with generation order. More strongly localized modes can be found from the symmetric Fibonacci superlattices than from the traditional Fabry-Perot resonators, which makes the proposed structure an attractive alternative to a wide variety of optoelectronic devices.
