Researchers developed a small, integrated spectrometer on a silicon chip using unique multi-point self-coupled waveguide filters. This device can measure a wide range of light wavelengths with high detail (large bandwidth and resolution) and operates reliably across a broad temperature range without needing extra cooling or heating, making it suitable for low-cost, portable applications.
