  • Publication number: 20230384156
    Abstract: An apparatus includes a substrate and an optically powered surface. The substrate is transmissive of electromagnetic energy, and includes a plurality of reflective portions oriented and positioned to control a propagation direction of electromagnetic energy along an optical path of the substrate. The substrate further includes an input surface aligned with the optical path so as to allow electromagnetic energy to enter the substrate through the input surface. The optically powered surface is positioned relative to the substrate so as to redirect a field of view of the substrate. The field of view of the substrate is bounded by a first angular width, a field of view of the optically powered surface is bounded by a second angular width, and the second angular width is different than the first angular width.

  • Patent number: 11353362
    Abstract: An apparatus includes a substrate transmissive of electromagnetic energy of at least a plurality of wavelengths, having a first end, a second end, a first major face, a second major face, at least one edge, a length, a width, and a thickness, at least a first output optic that outputs electromagnetic energy the substrate; and a first input optic oriented and positioned to provide electromagnetic energy into the substrate via at least one of the first or the second major face of the substrate. The first output optic is laterally spaced from the first input optic. A number of reflectors and optional absorbers may be positioned proximate the first major face and/or the second major face to structure electromagnetic energy and/or to translate such from the first input optic to the first output optic. The apparatus may be part of a spectrometer or other optical system.

  • Patent number: 9366571
    Abstract: Apparatus and methods can include an optical waveguide coupled to a photonic crystal comprising a dielectric material, the photonic crystal located on an exterior surface of the optical waveguide and comprising a first surface including a first array of periodic features on or within the dielectric material, the array extending in at least two dimensions and including an effective dielectric permittivity different from the surrounding dielectric material. In an example, the periodic features include a specified lattice constant, the periodic features configured to extract a portion of propagating optical energy from the waveguide through the photonic crystal, the portion determined at least in part by the specified lattice constant.
