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.

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.

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 nanostructure that selectively extracts electromagnetic energy of a first set of wavelengths from the substrate; and an 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. Nanostructures can take the form of photonic crystal arrays, a plasmonic structure arrays, or holographic diffraction gratings. The apparatus may be part of a spectrometer.
