Metasurface-engineered thermal emitters enabled chip-scale mid-infrared spectroscopic sensing by Qin Chen, Hu Nie, Qinke Liu, Ning Tan, Ziwang Tuo, Jiahao Yan, Long Wen

“…Little attention was paid on light sources, while light source and its optical collimation unit left unsaid in most miniaturized spectrometers actually dominate a majority of the footprint and the cost of the entire platform. Here, we demonstrate light-source engineering as a new paradigm for developing a miniaturized spectroscopic sensing platform in mid-infrared (MIR), where spectral information of the analyte is encoded in the MIR image of a chip-size thermal source. …”
