In contrast to cumbersome benchtop spectrometers. integrated on-chip spectrometers are well-suited for portable applications in health monitoring and environmental sensing. In this paper. we have developed an on-chip spectrometer with a programmable silicon photonic filter by simply using parallel cascaded micro-ring resonators (MRs). https://trendingcustomes.shop/product-category/4-in-1-can-cooler/
