Nanowires Can Be Tuned to Range of Wavelengths for Optoelectronics

Facebook Twitter LinkedIn Email
DRESDEN, Germany, July 2, 2019 — A research team at Helmholtz-Zentrum Dresden-Rossendorf (HZDR), in collaboration with researchers at Technische Universität (TU) Dresden and Deutsches Elektronen-Synchrotron (DESY) in Hamburg, has produced nanowires with operating wavelengths that can be tuned over a wide range by altering the structure of the nanowire’s shell. Fine-tuned nanowires could take on several roles in an optoelectronic component, making the component more powerful, cost-effective, and easier to integrate. The researchers grew gallium arsenide nanowires epitaxially on silicon substrates. Then they...Read full article

    GLOSSARY
    nanophotonics
    The study of how light interacts with nanoscale objects and the technology of applying photons to the manipulation or sensing of nanoscale structures.
    optoelectronics
    A sub-field of photonics that pertains to an electronic device that responds to optical power, emits or modifies optical radiation, or utilizes optical radiation for its internal operation. Any device that functions as an electrical-to-optical or optical-to-electrical transducer. Electro-optic often is used erroneously as a synonym.
