Abstract

Miniaturized spectrometers show great application potential in biology, medicine, astronomy and so on. However, it is still challenging to obtain broadband spectrum and high spectral resolution simultaneously with limited size. In this study, we proposed a single waveguide spectrometer based on light scattering of the defects buried in the waveguide. The detections of the scattering light are set on the upper surface of the waveguide, as a result, tremendous detection channels can be realized even within a small structure size, which makes simultaneously high resolution and broad bandwidth detection achievable. Simulation studies show that this kind of spectrometer can exhibits an impressive bandwidth of 1000 nm, ranging from 600 to 1600 nm. Additionally, a resolution of 0.2 nm is achieved within the range of 850 to 852 nm through fine sampling. The influence factors of the performance of the spectrometer is also studied. This work provides the possibility of achieving on-chip, high-resolution, and wide-bandwidth spectrometers.

微型光谱仪在生物学、医学、天文学等领域有着巨大的应用潜力。然而，在尺寸有限的情况下同时获得宽带光谱和高光谱分辨率仍是一项挑战。在这项研究中，我们提出了一种基于埋在波导中的缺陷的光散射的单波导光谱仪。散射光的检测器设置在波导的上表面，因此即使结构尺寸很小，也能实现巨大的检测通道，从而同时实现高分辨率和宽带宽检测。仿真研究表明，这种光谱仪的带宽可达 1000 nm，范围从 600 nm 到 1600 nm。此外，通过精细采样，在 850 至 852 nm 范围内可实现 0.2 nm 的分辨率。此外，还研究了光谱仪性能的影响因素。这项工作为实现片上、高分辨率和宽带光谱仪提供了可能性。
