Publication number: 20240173930Abstract: Methods are disclosed for fabricating molds for forming eyepieces having waveguides with integrated spacers. The molds are formed by etching deep holes (e.g., 5 ?m to 1000 ?m deep) into a substrate using a wet etch or dry etch. The etch masks for defining the holes may be formed with a thick metal layer and/or multiple layers of different metals. A resist layer may be disposed over the etch mask. The resist layer may be patterned to form a pattern of holes, the pattern may be transferred to the etch mask, and the etch mask may be used to transfer the pattern into the underlying substrate. The patterned substrate may be utilized as a mold onto which a flowable polymer may be introduced and allowed to harden. Hardened polymer in the holes may form integrated spacers. The hardened polymer may be removed from the mold to form a waveguide with integrated spacers.Type: ApplicationFiled: November 10, 2023Publication date: May 30, 2024Inventors: Mauro MELLI, Chieh Chang, Ling Li, Melanie Maputol WEST, Christophe Peroz, Ali KARBASI, Sharad D.

Patent number: 11954809Abstract: 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.Type: GrantFiled: April 29, 2022Date of Patent: April 9, 2024Assignee: Magic Leap, Inc.Inventors: Melanie Maputol West, Christophe Peroz, Mauro Melli

Publication number: 20240036321Abstract: In some embodiments, a near-eye, near-eye display system comprises a stack of waveguides having pillars in a central, active portion of the waveguides. The active portion may include light outcoupling optical elements configured to outcouple image light from the waveguides towards the eye of a viewer. The pillars extend between and separate neighboring ones of the waveguides. The light outcoupling optical elements may include diffractive optical elements that are formed simultaneously with the pillars, for example, by imprinting or casting. The pillars are disposed on one or more major surfaces of each of the waveguides. The pillars may define a distance between two adjacent waveguides of the stack of waveguides. The pillars may be bonded to adjacent waveguides may be using one or more of the systems, methods, or devices herein. The bonding provides a high level of thermal stability to the waveguide stack, to resist deformation as temperatures change.Type: ApplicationFiled: December 21, 2021Publication date: February 1, 2024Inventors: Ling Li, Christophe Peroz, Chieh Chang, Sharad D.

Publication number: 20230359036Abstract: A head-mounted, near-eye display system comprises a stack of waveguides having integral spacers separating the waveguides. The waveguides may each include diffractive optical elements that are formed simultaneously with the spacers by imprinting or casting. The spacers are disposed on one or more major surfaces of the waveguides and define a distance between immediately adjacent waveguides. Adjacent waveguides may be bonded using adhesives on the spacers. The spacers may fit within indentations of overlying waveguides. In some cases, the spacers may form one or more walls of material substantially around a perimeter of an associated waveguide. Vent holes may be provided in the walls to allow gas flow into and out from an interior volume defined by the spacers. Debris trapping structures may be provided between two walls of spacers to trap and prevent debris from entering into the interior volume.Type: ApplicationFiled: June 30, 2023Publication date: November 9, 2023Inventors: Ling Li, Christophe Peroz, Chieh Chang, Sharad D.
