Patent number: 12326584Abstract: An incident optical beam illuminates a subset of contiguous array of diffraction gratings on a substrate and produces one or more diffracted output beams. The grating array can be arranged so that (i) multiple incident beams result in a contiguous composite solid angle of far-field illumination, (ii) multiple output beams arising from any one incident beam do not overlap in the far field, or (iii) both. The gratings of the array can be arranged to produce a desired far-field illumination intensity profile. The grating array can be arranged so as to suppress or eliminate laser speckle arising from the output beams.Type: GrantFiled: January 24, 2024Date of Patent: June 10, 2025Assignee: II-VI DELAWARE, INC.Inventors: Thomas W. Mossberg, Jianji Yang, Dmitri Iazikov, Christoph M. Greiner

Publication number: 20250164695Abstract: An optical element includes a waveguide body that is configured to guide light by total internal reflection from an input end to an output end, an input coupling element located at the input end for coupling light into the waveguide body, and an output coupling element located at the output end for coupling light out of the waveguide body, where the waveguide body includes an organic solid crystal. The organic solid crystal may be a single crystal having principal axes rotated with respect to the dimensions of the waveguide body. Such an optical element may have low weight and exhibit good color uniformity while providing polarization scrambling of the guided light.Type: ApplicationFiled: July 26, 2024Publication date: May 22, 2025Inventors: Prathmesh Deshmukh, Tingling Rao, Zhaoyu Nie, Andrew John Ouderkirk, Jie Li, Yuanrui Li, Jianji Yang, Zhenye Li, Sawyer Miller, Xuan Wang, Joshua Cobb, Hsien-Hui Cheng, Eugene Cho, Robin Sharma, Eric Stratton, Ajit Ninan, Zhexin Zhao, Xiayu Feng, Yun-Han Lee, Michael Escuti, Steven John Robbins, Babak Amirsolaimani, Lu Lu, Barry David Silverstein

Patent number: 12204121Abstract: An optical element includes a substrate, an intermediate layer, a topmost layer, and a contiguous multitude of recessed and non-recessed areal regions. The intermediate layer is formed over a top surface of the substrate and has a refractive index nI. The topmost layer is formed directly on the intermediate layer and has a refractive index nT where nT?nI. The intermediate and topmost layers are substantially transparent over an operational wavelength range that includes a design wavelength ?0. A subset of areal regions has a largest transverse dimension less than about ?0. Each non-recessed areal region includes corresponding portions of the intermediate and topmost layers. Each recessed areal region extends entirely through the topmost layer and at least partly through the intermediate layer. A fill medium fills the recessed areal regions. The areal regions are variously sized and distributed transversely across the optical element.Type: GrantFiled: March 29, 2022Date of Patent: January 21, 2025Assignee: II-VI DELAWARE, INC.Inventors: Christoph M. Greiner, Jianji Yang, Dmitri Iazikov

Patent number: 11841518Abstract: Certain examples are directed to optical elements or devices that pass or process the light based on a set of connectable metasurface elements having been topology optimized. The connectable metasurface elements are independently optimized or designed to have each section having its own metasurface phase profile corresponding to a desired phase profile. In this way, such devices need not be designed or manufactured by importing a large number of results into simulation efforts, thereby realizing significant saving in terms of optimization time and computational power.Type: GrantFiled: April 29, 2020Date of Patent: December 12, 2023Assignee: The Board of Trustees of the Leland Stanford Junior UniversityInventors: David Sell, Jonathan A.
