提出并研究了一种基于金属-绝缘体-金属（MIM）三波导的紧凑纳米表面等离子激元法布里-珀罗滤波器。采用时域有限差分法和法布里-珀罗共振模型分析了该SPP带通滤波器的特性。结果表明，谐振腔长度可以线性改变通带的共振波长，通过改变MIM波导之间的间隙可以改变通带的透射比。同时考虑了金属损耗和色散对SPP滤波器光谱的影响。这种简单的滤波器在高密度SPP波导集成中非常有前景。(C) 2010 Elsevier B.V.版权所有
A compact nanometric surface plasmon polariton Fabry-Perot filter based on three metal-insulator-metal (MIM) waveguides is proposed and studied. The characteristics of this SPP band pass filter are analyzed by the finite difference time domain method and the Fabry-Perot resonance model. The results show that the resonance wavelengths of the pass bands can be linearly changed by the resonant cavity length, and the transmission ratios of the pass bands can be varied by altering the gaps between the MIM waveguides. The metal loss and dispersion effects on the SPP filter's spectra are considered as well. This kind of simple filter is very promising for high density SPP waveguide integrations.
