Clinical, Commercial Applications Loom for Ultracompact On-Chip Spectrometer

Facebook Twitter LinkedIn Email Comments
NEW HAVEN, Conn., June 10, 2021 — An ultracompact, mid-infrared spectrometer that uses a 10-nm thick, single tunable black phosphorus photodetector shows promise as an on-chip device for sensing, surveillance, and spectral imaging. The device is the result of a collaboration among scientists from Yale University, Bar-Ilan University (Israel), and the National Institute of Materials Science (Japan). The spectrometer has an active area footprint of only 9 × 16 µm2. It measures light in the 2- to 9-µm spectral range and was constructed at the scale of the operational wavelength.
