Miniaturization of optical spectrometers

Miniaturizing spectrometers Optical spectroscopy is a widely used characterization tool in industrial and research laboratory settings for chemical fingerprinting analysis. High-end are typically benchtop based with bulky optical components, moving parts, long path lengths, they can deliver wealth of information ultrahigh precision bandwidth. There is, however, drive toward miniaturization spectrometers, which concepts nanophotonics to control light on much smaller scales. Yang et al. reviewed recent developments spectrometry systems, including various fabrication approaches systems the software that computationally determines spectra, strive shrink their footprint open up applications portable spectroscopy.
