Publication number: 20240134198Abstract: An augmented-reality (AR) eyewear display utilizes an optical waveguide having multi-layered optical gratings in a repeating arrangement. The optical gratings include varying depths, slope angles, lengths, and/or widths in order to tune the gratings to provide an improved AR eyewear display. By using the different configurations of two-dimensional or three-dimensional gratings disclosed herein in a waveguide of an AR eyewear display, optical characteristics of the waveguide are optimized to provide, e.g., high resolution and/or contrast, high display uniformity, high input coupling efficiency, and/or high output coupling efficiency. Accordingly, in some embodiments, aspects of the present disclosure enable lower-power AR eyewear displays to produce the same quality of display of a higher-power conventional AR eyewear display waveguide.Type: ApplicationFiled: September 24, 2023Publication date: April 25, 2024Inventors: Wei Jin, Joseph Daniel Lowney, Lu Tian, Qinglan Huang, Thomas Mercier

Publication number: 20240094517Abstract: Disclosed herein are methods and systems that use a photonic crystal (PC) for interference scattering microscopy. Incident light is directed onto a surface of the PC and couples into a photonic crystal guided resonance (PCGR) mode of the PC such that less than 1% of the incident light is transmitted through the PC as transmitted light. One or more particles adjacent to the surface of the PC scatter a portion of the light coupled into the PCGR mode as scattered light. An image comprising a pattern of constructive and destructive interference between the transmitted light and the scattered light is formed, and an image sensor may capture one or more image frames of the image Imaging processing of the one or more image frames can be used to identify at least one scattering center corresponding to at least one particle of the one or more particles.Type: ApplicationFiled: February 3, 2022Publication date: March 21, 2024Inventors: Brian T. CUNNINGHAM, Nantao LI, Taylor D. CANADY, Qinglan HUANG, Xing WANG
