摘要

我们提出并数值分析了一种宽带、超紧凑的混合等离子体模式转换器/偏振旋转器。所提出的器件将基频横向磁模(TM 0)转换为一阶横向电模(TE 1)。该模式转换器采用锥形混合等离子体波导设计,其中金属部件直接包围输入硅波导和锥形输出波导,而没有薄的低折射率层。经过结构优化,实现了模态转换效率为98.2%的TM 0 - te 1模式转换器。实现了100nm的宽工作带宽,整个器件的紧凑占地面积仅为0.8µm×12.5µm。在1550 nm波长下,不同金属材料的插入损耗范围为0.91 ~ 1.19 dB,输出Si波导中TE 1和TM 0模式的消光比均高于21 dB。

Highly efficient silicon mode converter andpolarization rotator using a silicon-based hybridplasmonic waveguide
We propose and numerically analyze a broadband, ultracompact hybrid plasmonic mode converter/polarization rotator. The proposed device converts the fundamental transverse magnetic mode (TM 0 ) to the first-order transverse electric mode (TE 1 ). The mode converter is designed using a tapered hybrid plasmonic waveguide in which metal parts are directly surrounding both the input Si waveguide and the tapered output waveguide without a thin low-index layer. After optimizing the proposed structure, a TM 0 -to-TE 1 mode converter with a modal conversion efficiency of 98.2% is achieved. A broad operating bandwidth of 100 nm is achieved with a compact footprint of only 0.8µm×12.5µm for the whole device. At a wavelength of 1550 nm, the insertion loss ranges from 0.91 dB to 1.19 dB using different metal materials, and the extinction ratio of the TE 1 and TM 0 modes is higher than 21 dB in the output Si waveguide.
