    Abstract: Fabricating a high refractive index photonic device includes disposing a polymerizable composition on a first surface of a first substrate and contacting the polymerizable composition with a first surface of a second substrate, thereby spreading the polymerizable composition on the first surface of the first substrate. The polymerizable composition is cured to yield a polymeric structure having a first surface in contact with the first surface of the first substrate, a second surface opposite the first surface of the polymeric structure and in contact with the first surface of the second substrate, and a selected residual layer thickness between the first surface of the polymeric structure and the second surface of the polymeric structure in the range of 10 μm to 1 cm. The polymeric structure is separated from the first substrate and the second substrate to yield a monolithic photonic device having a refractive index of at least 1.6.

    IPC: F21V8/00

    Abstract: A multi-waveguide optical structure, including multiple waveguides stacked to intercept light passing sequentially through each waveguide, each waveguide associated with a differing color and a differing depth of plane, each waveguide including: a first adhesive layer, a substrate having a first index of refraction, and a patterned layer positioned such that the first adhesive layer is between the patterned layer and the substrate, the first adhesive layer providing adhesion between the patterned layer and the substrate, the patterned layer having a second index of refraction less than the first index of refraction, the patterned layer defining a diffraction grating, wherein a field of view associated with the waveguide is based on the first and the second indices of refraction.

    Abstract: Methods, systems, and apparatus for a substrate transfer method, including positioning a tray handler device in a first position with i) cutouts of an aperture of the first tray in superimposition with respective pedestals of a pedestal platform and ii) a distal end of the pedestals extending away from a top surface of the first tray; increasing a distance between the top surface of the first tray and a top surface of the pedestal platform to transfer a first substrate from the pedestals to the tabs defined by the aperture of the first tray, while concurrently engaging the second tray handler with the second tray; and increasing a distance between the top surface of the second tray and the bottom surface of a chuck to transfer a second substrate from the chuck to the tabs defined by the second tray.

    Abstract: A method of generating a virtual image, including directing a light beam to a first side of an eyepiece, including transmitting the light beam into a first waveguide of the eyepiece; deflecting, by first diffractive elements of the first waveguide, a first portion of the light beam towards a second waveguide of the eyepiece, the first portion of the light beam associated with a first phase of light; deflecting, by protrusions on the first side of the eyepiece, a second portion of the light beam towards the second waveguide, the second portion of the light beam associated with a second phase of light differing from the first phase; and deflecting, by second diffractive elements of the second waveguide, some of the first and the second portions of the light beam to provide an exiting light beam associated with the virtual image that is based on the first and second phases.
