  • METHOD AND APPARATUS FOR FABRICATION OF LARGE THREE-DIMENSIONAL SINGLE COLLOIDAL CRYSTALS FOR BRAGG DIFFRACTION OF INFRARED LIGHT
    Publication number: 20230393330
    Abstract: A three-dimensional Bragg grating may include a single colloidal crystal that includes a plurality of repeated layers of material having different refractive indexes. A sample cell for producing a volume Bragg grating may include an internal shape that forms at least one capillary cell having a flat surface and rounded edges. A method of producing a three-dimensional Bragg grating may include: suspending insoluble particles in a host fluid to form a suspension; and exposing the suspension to a sustained microgravity environment.
