Spectrometers are widely used throughout industry and research to detect and analyze light. Spectrometers measure the spectrum of light—its strength at different wavelengths, like the colors in a rainbow—and are an essential tool for identifying and analyzing specimens and materials. Integrated on-chip spectrometers would be of great benefit to a variety of technologies, including quality inspection platforms, security sensors, biomedical analyzers, health care systems, environmental monitoring tools, and space telescopes.

An international research team led by researchers at Aalto University has developed high-sensitivity spectrometers with high wavelength accuracy, high spectral resolution, and broad operation bandwidth, using only a single microchip-sized detector.
