Abstract: The present disclosure relates to display systems and, more particularly, to augmented reality display systems. In one aspect, a method of fabricating an optical element includes providing a substrate having a first refractive index and transparent in the visible spectrum. The method additionally includes forming on the substrate periodically repeating polymer structures. The method further includes exposing the substrate to a metal precursor followed by an oxidizing precursor. Exposing the substrate is performed under a pressure and at a temperature such that an inorganic material comprising the metal of the metal precursor is incorporated into the periodically repeating polymer structures, thereby forming a pattern of periodically repeating optical structures configured to diffract visible light. The optical structures have a second refractive index greater than the first refractive index.

Abstract: The present disclosure generally relates to display systems, and more particularly to augmented reality display systems and methods of fabricating the same. A method of fabricating a display device includes providing a substrate comprising a lithium (Li)-based oxide and forming an etch mask pattern exposing regions of the substrate. The method additionally includes plasma etching the exposed regions of the substrate using a gas mixture comprising CHF3 to form a diffractive optical element, wherein the diffractive optical element comprises Li-based oxide features configured to diffract visible light incident thereon.

Abstract: An optical system comprises an optically transmissive substrate comprising a multilevel metasurface which comprises a grating comprising a plurality of multilevel unit cells. Each unit cell comprises, on a lowermost level, a laterally-elongated first lowermost level nanobeam having a first width and a laterally-elongated second lowermost level nanobeam having a second width larger than the first width. Each unit cell further comprises, on an uppermost level, a laterally-elongated first uppermost level nanobeam above the first lowermost level nanobeam and a laterally-elongated second uppermost level nanobeam above the second lowermost level nanobeam.

Abstract: A Procedural EBL system implements a user-provided oracle function (e.g., associated with a specific pattern) to generate control instructions for electron beam drive electronics in an on-demand basis. A control system may invoke the oracle function to query the pattern at individual point locations (e.g., individual x,y locations), and/or it may query the pattern over an area corresponding to a current field being addressed by the beam and stage positioner, for example. This Procedural EBL configuration manages control and pattern generation so that the low-level drive electronics and beam column may remain unchanged, allowing it to leverage existing EBL technologies.

Abstract: A method of manufacturing a waveguide having a combination of a binary grating structure and a blazed grating structure includes cutting a substrate off-axis, depositing a first layer on the substrate, and depositing a resist layer on the first layer. The resist layer includes a pattern. The method also includes etching the first layer in the pattern using the resist layer as a mask. The pattern includes a first region and a second region. The method further includes creating the binary grating structure in the substrate in the second region and creating the blazed grating structure in the substrate in the first region.

Abstract: An optical system comprises an optically transmissive substrate comprising a metasurface which comprises a grating comprising a plurality of unit cells. Each unit cell comprises a laterally-elongated first nanobeam having a first width; and a laterally-elongated second nanobeam spaced apart from the first nanobeam by a gap, the second nanobeam having a second width larger than the first width. A pitch of the unit cells is 10 nm to 1 μm. The heights of the first and the second nanobeams are: 10 nm to 450 nm where a refractive index of the substrate is more than 3.3; and 10 nm to 1 μm where the refractive index is 3.3 or less.

Abstract: In some embodiments, a display device includes one or more waveguides having a vapor deposited light absorbing film on edges of the waveguide to mitigate ghost images. In some embodiments, the film is formed directly on the edge of the waveguide by a vapor deposition, such as an evaporative deposition process. In some embodiments, the light absorbing films may comprise carbon, for example carbon in the form of one or more allotropes of carbon, such as fullerenes, or black silicon.
