US Patent 10,031,288 issued to Etaphase: “Optical structures and hyperuniform disordered material “ Abstract follows: An optical structure and a system includes a Hyperuniform Disordered Solid (“HUDS”) structure and a waveguide. The HUDS structure is formed by walled cells organized in a lattice.
Etaphase’s US9,720,172 patent issued. “Hyperuniform disordered material with resonant structures” Abstract follows: 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.
US Patent Office issues US9,519,104 to Etaphase Abstract follows: 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.
