中文摘要:设计并研究了基于金属-介质-金属(MIM)等离子体环形谐振器的可调谐高性能多通道波分解复用器(WDM)。通过环形腔的谐振理论分析,发现通过调节环形腔的半径和填充介质折射率可以很容易地控制波分复用器的信道波长,与有限元法(FEM)模拟得到的结果吻合得很好。由等离子体波导和多个环形谐振器组成的多信道WDM结构增加了在电信波长的传输率,传输率高达80%,比最近文献中报道的结果高出两倍。所设计的多信道波分解复用器在高集成电路中有重要潜在应用。

A new design of tunable high performance multi-channel optical demultiplexer based on MIM plasmonic ring resonators at telecommunication wavelengths
Abstract:The tunable high performance multi-channel wavelength demultiplexer (WDM) based on metal-insulator-metal (MIM) plasmonic ring resonators is designed and numerically investigated. By the resonant theory of ring cavity, we find that the channel wavelength of WDM can be easily manipulated by adjusting the radius and refractive index of the ring cavity, which is in good agreement with the results obtained by finite element method (FEM) simulations. The multi-channel WDM structure consisting of a plasmonic waveguide and several ring resonators increases the transmission up to 80% at telecommunication regime, which is two times higher than the results reported in a recent literature. The proposed compact multi-channel wavelength demultiplexer can find more applications for the ultra-compact WDM systems in highly integrated telecommunication circuits.
