Abstract
Spectral routing techniques have attracted plenty of research attention for the past decades, as they enable light manipulation in both the frequency domain and the spatial domain, which is crucial for applications in on-chip spectroscopy, optical switching, and modern communications. Here, we demonstrate an ultra-compact asymmetric nanoplasmonic router for communication bands that routes O and C bands to opposite positions. The nanorouter consists of two uneven grooves that create bidirectional scattered optical fields, utilizing the interference between different optical modes inside the grooves. A broadband spectrum exceeding 100 nm and a maximum extinction ratio of 31 dB are achieved, providing new opportunities for nanophotonic color routing solutions and extensions to other areas such as imaging sensors and spectral measurements.
过去几十年来,光谱路由技术吸引了大量研究人员的关注,因为它们可以在频域和空间域对光进行操纵,这对于片上光谱学、光开关和现代通信中的应用至关重要。在这里,我们展示了一种用于通信波段的超紧凑非对称纳米光电路由器,它能将 O 波段和 C 波段路由到相反的位置。该纳米路由器由两个凹凸不平的凹槽组成,利用凹槽内不同光学模式之间的干涉,产生双向散射光场。实现了超过 100 nm 的宽带光谱和 31 dB 的最大消光比,为纳米光子色彩路由解决方案提供了新的机遇,并扩展到成像传感器和光谱测量等其他领域。
