Imperfections Untether Quantum Sensors from Bulky Optics
GAITHERSBURG, Md., Nov. 30, 2023 — By adding tiny, periodic bumps to a microresonator, researchers were able to convert near-infrared (NIR) laser light into specific desired wavelengths of visible light with high accuracy and efficiency. Developed by the National Institute of Standards and Technology (NIST) and its colleagues at the Joint Quantum Institute (JQI), a research partnership between the University of Maryland and NIST, the technique has potential applications in precision timekeeping and quantum information science,
