摘要

这封信提出了基于数字化超材料的50:50 TE太赫兹功率分离器。采用粒子群优化算法对组件进行优化。数字化的超材料形成在二氧化硅衬底上带有圆形气孔的硅板。在0.87 ~ 1.09 THz频率范围内,半径为9 μm的气孔和半径不同(9 μm和7 μm)的气孔的插入损耗分别小于3.9 dB和3.65 dB。器件尺寸为400 μm × 350 μm。该器件具有紧凑、高效、全介电特性和与CMOS制造技术兼容等优良特性,可以成为大多数太赫兹波路由电路的重要组成部分。

Inverse Design of Terahertz Optical Power Splitters Using the Particle Swarm Optimization Method
This letter proposes 50:50 TE terahertz power splitters based on digitized metamaterials. The components are optimized using the particle swarm optimization algorithm. The digitized metamaterials are formed as a silicon slab with circular air holes atop a silicon dioxide substrate. The insertion losses of optimized structures containing air holes with a radius of 9 μm and air holes with different radii (9 μm and 7 μm) are less than 3.9 dB and 3.65 dB, respectively, over a frequency range of 0.87–1.09 THz. The footprint of the proposed devices is 400 μm × 350 μm. The devices have excellent characteristics, such as compactness, efficiency, all-dielectric properties, and compatibility with CMOS fabrication technologies, and can become vital components of most terahertz-wave routing circuits.
