摘要： A system may include a meta-surface including multiple unit cells arranged along the meta-surface. Structural parameters of each unit cell may vary along the meta-surface. The system may further include at least a first active feed unit directed toward the meta-surface to generate a first beam. The first active feed unit may be configured to move relative to the meta-surface parallel to a 2-dimensional plane. The first beam is steerable by moving the first active feed unit.

摘要： Chemical (e.g., click chemistry), enzymatic- or photo-induced polymerization or other polymerization approaches (e.g., thermally activated) of (1) single dyes (monomer) can be used to produce an extended dye network in which each successive dye is arranged in a head-to-tail arrangement (J-like packing arrangement) of their transition dipole moments or (2) dye aggregate sub-units to achieve polymer branching. Furthermore, various routing patterns are achieved by templating a linear series of dyes onto DNA oligomers of various configurations. Dye aggregate dye sub-unit junctions (e.g., triad, tetrad, pentad, hexad, etc.) are used to achieve polymer branching enable creating various circuit patterns and circuit elements (e.g., optical transistors, gates, etc.). Branched configurations can occur on any surface (e.g., DNA nanostructure, chips substrate, hydrogel, etc.) using DNA (or any similar specific [bio]chemistry).

摘要： A system is described that exhibits the functionality of a beam-splitter, typically an optical device that splits a beam of light in two. In this case, the beams are acoustic pulses and can lead to the creation of a Wannier-Mott exciton: a bound state of an electron and an electron hole whose attraction to each other is maintained by the electrostatic Coulomb force. This exciton beam-splitter is lossy (i.e., involves the dissipation of electrical or electromagnetic energy). Half of the time the exciton is radiated away. Nevertheless, if the exciton is not lost, the exciton is now in a superposition of two states that can be well separated in position. Four such beam-splitters can be used to make an exciton interferometer that uses the interference patterns from the interacting acoustic pulses to extract information.

摘要： Dye aggregates that are templated to deoxyribonucleic acid (DNA) can exhibit different packing arrangements and, as an optically active medium, spectral properties of interest. Steric effects and properties of the linker that tethers the dye to a DNA scaffold (a simple nucleotide oligomer or more complex architectures) can used to fine tune the packing arrangement of the dyes to obtain desirable spectral properties. To gain access to J-aggregates (head-to-tail packing arrangement) as a source of fluorescent materials, the present disclosure is directed to two strategies that utilize rigid linkers to promote J-packing. Devices and methods of use also are disclosed herein.

摘要： The present disclosure is directed to designing dyes and methods to alter the parameters controlling the dipole-dipole coupling of dyes bound to a nucleotide oligomer architecture, which are used to propagate excitons for use in next generation room temperature quantum information systems. The disclosed dyes and methods are directed to changing the dye stability, symmetry, overlap, and steric hindrance of the dyes to fine tune aggregate systems.

摘要： Compositions and methods for encoding and retrieving data into nucleic acid memory for storage. More specifically, data is encoded into spatial locations within a nucleic acid architecture, which allows the data to be retrieved using super resolution microscopy. The data is then interrogated for errors, the errors corrected, and the data is then decoded.

摘要： An apparatus, system, and method for detecting light having a specified or first wavelength. The apparatus includes a substrate that generates charge separation in the presence of light having the first wavelength. An active material is deposited onto the substrate. The active material is configured to conduct current in the presence of light having a second wavelength. Two electrodes are connected to the active material. Light having the second wavelength is constantly applied to the active material and the current is monitored via the electrodes. The active material will conduct zero or minimal current via the electrodes if the substrate does not generate charge separation. Detection the presence of light having the first wavelength may be detected upon the detection of current via the two electrodes. The first wavelength may be non-visible light and the second wavelength may be visible light.
