Single-Nanowire Spectrometer Works Separately from Components
CAMBRIDGE, England, Sept. 9, 2019 — Scientists at the University of Cambridge have developed a microspectrometer based on a single, compositionally engineered nanowire that is independent of the complex optical components or cavities that tend to constrain further miniaturization of current systems. According to the researchers, it is the smallest spectrometer ever designed. The Cambridge team, working with colleagues from China, England, and Finland, used a nanowire whose material composition varied along the length of the
