慢光器件由于在未来光网络和信息处理系统中的潜在应用而受到广泛关注。本文提出了两种具有超材料特性的硅线波导，并利用基于均匀化的模式分析方法分析了其慢光效应。推导的色散关系表明，在超材料谐振频率附近，当传输损耗为0.7dB/μm时，可以获得大于70的群折射率。
Slow-light devices have been attracting a great amount of attention owing to their potential applications in future optical networks and information-processing systems. In this paper we propose two types of silicon wire waveguides with metamaterials, which are potentially applicable to the deceleration of light speed, and we analyze the slow-light effect by using the homogenization-based mode analysis method. The derived dispersion relation indicates that a group index larger than 70 can be obtained with a propagation loss of ∼0.7 dB/μm near the resonant frequency of the metamaterial.
