论文摘要
我们证明了一个基于多模干扰的光谱仪（40 $ $ m $ m $ \ times $ 260 $ $ m），这是通过在硅在制剂仪平台上从随机SIO $ _2 $填充的孔阵列中散射出来的。我们表征了在1310 nm左右波长的光谱仪的性能，并报告光谱仪可以重建宽带$ \ sim $ 67 nm源，以及$ \ sim $ 1 nm bandwidth的洛伦兹探针。这种紧凑的纳米水平分辨率光谱仪可以以低成本来制造，以用于实验室芯片接触和成像应用。
We demonstrate a compact (40 $μ$m $\times$ 260 $μ$m) spectrometer based on multimode interference aided by scattering of light from random SiO$_2$-filled hole arrays on a silicon-on-insulator platform. We characterize the performance of the spectrometer for wavelengths around 1310 nm, and report that the spectrometer can reconstruct a broadband $\sim$ 67 nm source, as well as Lorentzian probes of $\sim$ 1 nm bandwidth. This compact nanometer level resolution spectrometer can be fabricated at a low cost for lab-on-a-chip sensing and imaging applications.
