  • Method and apparatus for manufacturing photonic crystals
    Patent number: 11473213
    Abstract: A method of making a liquid dispersion for the manufacture of a photonic crystal. The method comprises dispersing monodispersed spheres in a liquid to form a liquid dispersion, and subjecting the liquid dispersion to an ultrasonic treatment. Ammonia solution may also be added to the liquid dispersion. The ultrasound treatment breaks up agglomerations of monodispersed spheres, and the resulting photonic crystal made using the dispersion is more highly ordered and hence of higher quality.
    Type: Grant
