Appl. No.:

17/098187

Inventors:

- Menlo Park CA, US
Austin LANE - Bellevue WA, US
Matthew E. COLBURN - Woodinville WA, US

International Classification:

C07C 271/54
G03H 1/02

Abstract:

The disclosure provides recording materials including aromatic substituted ethane-core derivatized monomers and polymers for use in volume Bragg gratings, including, but not limited to, volume Bragg gratings for holography applications. Several structures are disclosed for monomers and polymers for use in Bragg gratings applications, leading to materials with higher refractive index, low birefringence, and high transparency. The disclosed derivatized monomers and polymers thereof can be used in any volume Bragg gratings materials, including two-stage polymer materials where a matrix is cured in a first step, and then the volume Bragg grating is written by way of a second curing step of a monomer.

Appl. No.:

16/877988

Inventors:

- Menlo Park CA, US
Qi Zhang - Kirkland WA, US
Andrew John Ouderkirk - Redmond WA, US
Matthew E Colburn - Woodinville WA, US

International Classification:

F21V 8/00
G02B 27/01

Abstract:

An optical element includes a transparent layer, outcoupling elements, and a waveguide structure. The outcoupling elements are positioned across the transparent layer. The waveguide structure provides non-visible light to the outcoupling elements and the outcoupling elements outcouple the non-visible light as non-visible illumination light to illuminate an eye region.

Abstract:

The disclosure provides recording materials include fluorene derivatized monomers and polymers for use in volume Bragg gratings, including, but not limited to, volume Bragg gratings for holography applications. Several fluorene structures are disclosed: simply substituted fluorenes, cardo-fluorenes, and spiro-fluorenes. Fluorene derivatized polymers in Bragg gratings applications lead to materials with higher refractive index, low birefringence, and high transparency. Fluorene derivatized monomers/polymers can be used in any volume Bragg gratings materials, including two-stage polymer materials where a matrix is cured in a first step, and then the volume Bragg grating is written by way of a second curing step of a monomer.

US Patent:

Appl. No.:

16/865022

Inventors:

- Menlo Park CA, US
Matthew E. COLBURN - Woodinville WA, US

International Classification:

C08F 283/00
G02B 5/02
G02B 5/18
G02B 5/20
G02B 1/04
C08F 2/48

Abstract:

The disclosure provides specific initiator/mediator chemistry for latent imaging polymers for volume Bragg gratings. Light mediated chemistry including the use of nitroxides allows a first step imaging to occur, where a light induced pattern is recorded in the material, without the grating being apparent. A second bleaching/developing step completes the curing process and reveals the grating.
