摘要

我们提出了一种在折射率波导表面等离子体波导中使用双模干涉耦合的紧凑型光功率分路器。该器件由硅芯、银上下包层和二氧化硅侧包层组成。通过基于有效折射率法的数值分析，研究了该器件的耦合特性，并从理论上说明了该器件在0.6328 ilm波长下作为紧凑型光功率分配器的应用。3dB功率分割比的器件长度估计为334 nm，比先前发表的作品小约rv313倍和约1.31倍。

SPP Based Compact Optical Power Splitter Using Two-Mode Interference Coupling

We have proposed a compact optical power splitter using two-mode interference (TMI) coupling in an index guided surface plasmonic waveguide. The device is made up of silicon core, silver upper and lower cladding and silicon dioxide side claddings. By using a numerical analysis based on effective index methods, the coupling characteristics of the device are studied and its application as a compact optical power splitter is shown theoretically for a wavelength of O.6328ILm. The device length for a 3dB power splitting ratio is estimated as 334 nm which is about rv313 times and ~1.31 times smaller than a previously published works.
