  • Publication number: 20200049998
    Abstract: An optical device includes a range of angularly selective reflectors are contained within an optical waveguide substrate and substantially optimized according to their reflector order within the sequence of reflectors. This configuration of reflectors ensures that the required angular information is passed through to the correct reflector within the sequence. The angular response in addition reduces or eliminates formation of secondary images carried to successive reflectors, resulting in undesired artefacts.

  • Patent number: 9879112
    Abstract: The present invention is related to novel preparative methods to a novel class of polymer network materials with a highly branched poly(glycidyl ether) (PGE) structure. Said polymer networks are prepared by a simple procedure involving ring-opening polymerisation and the method is applicable to a wide range of glycidyl ether containing monomers. The method comprises the step of copolymerising (A) at least one multi-topic glycidyl ether comprising at least three glycidyl ether groups with (B) at least one glycidyl ether component comprising at least one glycidyl ether group by ring opening polymerisation, wherein the multi-topic glycidyl ether (A) is glycerol glycidyl ether (GGE) having the Formula (I) and the glycidyl ether component (B) is selected from monoglycidyl ethers comprising one glycidyl ether group and diglycidyl ethers comprising two glycidyl ether groups.
