Abstract Chip-scale microspectrometers, operational across the visible to long-wave infrared spectral region will enable many remote sensing spectroscopy applications in a variety of fields including consumer electronics, process control in manufacturing, as well as environmental and agricultural monitoring. The low weight and small device footprint of such spectrometers could allow for integration into handheld, unattended vehicles or wearable-electronics based systems. This review will focus on recent developments in nanophotonic microspectrometer designs, which fall into two design categories: (i) planar filter-arrays used in conjunction with visible or IR detector arrays and (ii) microspectrometers using filter-free detector designs with tailored responsivities, where spectral filtering and photocurrent generation occur within the same nanostructure.

基于具有定制响应度和多光谱滤波器的光电探测器的长波红外芯片级光谱仪可见光

摘要 芯片级显微光谱仪可在可见光到长波红外光谱范围内运行，这将使许多遥感光谱应用在各个领域中成为可能，包括消费电子、制造过程控制以及环境和农业监测。这种光谱仪的重量轻和设备占用空间小，可以集成到手持式无人值守车辆或基于可穿戴电子设备的系统中。本综述将重点关注纳米光子显微光谱仪设计的最新发展，这些设计分为两个设计类别：(i) 与可见光或红外探测器阵列结合使用的平面滤光片阵列和 (ii) 使用具有定制响应度的无滤光片探测器设计的微光谱仪，
