  • Patent number: 9720172
    Abstract: An optical structure includes a Hyperuniform Disordered Solid (“HUDS”) structure, a waveguide, and a resonant cavity. The HUDS structure is formed by walled cells organized in a lattice. The waveguide is configured to guide an optical signal. The resonant cavity is formed along a boundary of the waveguide. The resonant cavity is configured to be resonant at a frequency band that is a subset of a bandwidth of the optical signal.

  • 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.
