Narrow-band frequency filters and splitters, photonic sensors, and cavities having pre-selected cavity modes

This invention relates generally to the field of quasicrystalline structures.

Controlled design of localized states in photonic quasicrystals

This invention relates generally to the field of quasicrystalline strictures. In preferred embodiments, the stopgap structure is more spherically symmetric than periodic structures facilitating the formation of stopgaps in nearly all directions because of higher rotational symmetries. More particularly, the invention relates to the use of quasicrystalline structures for optical, mechanical, electrical and magnetic purposes. In some embodiments, the invention relates to manipulating, controlling, modulating and directing waves including electromagnetic, sound, spin, and surface waves, for pre-selected range of wavelengths propagating in multiple directions.

Quasicrystalline structures and uses thereof

This invention relates generally to the field of quasicrystalline structures. In preferred embodiments, the stopgap structure is more spherically symmetric than periodic structures facilitating the formation of stopgaps in nearly all directions because of higher rotational symmetries. More particularly, the invention relates to the use of quasicrystalline structures for optical, mechanical, electrical and magnetic purposes. In some embodiments, the invention relates to manipulating, controlling, modulating and directing waves including electromagnetic, sound, spin, and surface waves, for pre-selected range of wavelengths propagating in multiple directions.

This invention is in the field of physical chemistry and relates to novel hyperuniform and nearly hyperuniform random network materials and methods of making said materials. Methods are described for controlling or altering the band gap of a material, and in particular commercially useful materials such as amorphous silicon. These methods can be exploited in the design of semiconductors, transistors, diodes, solar cells and the like.

Hyperuniform and nearly hyperuniform random network materials

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.
