  • Patent number: 10175389
    Abstract: The invention provides an article of manufacture, and methods of designing and making the article. The article permits or prohibits waves of energy, especially photonic/electromagnetic energy, to propagate through it, depending on the energy band gaps built into it. The structure of the article may be reduced to a pattern of points having a hyperuniform distribution. The point-pattern may exhibit a crystalline symmetry, a quasicrystalline symmetry or may be aperiodic. In some embodiments, the point pattern exhibits no long-range order. Preferably, the point-pattern is isotropic. In all embodiments, the article has a complete, TE- and TM-optimized band-gap. The extraordinary transmission phenomena found in the disordered hyperuniform photonic structures of the invention find use in optical micro-circuitry (all-optical, electronic or thermal switching of the transmission), near-field optical probing, thermophotovoltaics, and energy-efficient incandescent sources.

  • Patent number: 9519104
    Abstract: An optical structure includes a Hyperuniform Disordered Solid (“HUDS”) structure, a photonic crystal waveguide, and a perforated resonant structure. The HUDS structure is formed by walled cells organized in a lattice. The photonic crystal waveguide is configured to guide an optical signal and includes an unperforated central strip extended lengthwise and three rows of circular perforations disposed on each side of the unperforated central strip. The perforated resonant structure is formed along a boundary of the photonic crystal waveguide. The perforated resonant structure is configured to be resonant at a frequency band that is a subset of a bandwidth of the optical signal. The perforated resonant structure includes an outer segment, a middle segment, and an inner segment of the circular perforations that are offset away from the unperforated central strip at a first, second, and third offset distance.
