  • Optical structures including nanocrystals
    Patent number: 9910215
    Abstract: An optical structure can include a nanocrystal on a surface of an optical waveguide in a manner to couple the nanocrystal to the optical field of light propagating through the optical waveguide to generate an emission from the nanocrystal. The structure can be configured to restrict propagation of the emission from the nanocrystal along the waveguide.
    Type: Grant
    Filed: September 22, 2014
    Date of Patent: March 6, 2018
    Assignee: MASSACHUSETTS INSTITUTE OF TECHNOLOGY
    Inventors: Vladimir Bulovic, David H. Friend, Moungi Bawendi
