Dr. Marian Florescu garners an “Impact Acceleration Award (IAA)”

University of Surrey awards Etaphase co-founder Dr. Marian Florescu an “Impact Acceleration Award (IAA)” entitled “Lambertian Solar-Cell Absorbers” in the amount of £18,067 for collaborative work with Etaphase. This award from University of Surrey where Dr Florescu is a Senior Lecturer was funded by the UK’s Engineering Physical Sciences Research Council provides mutual in-kind support to Etaphase’s NSF SBIR Programs.  

Hyperuniform disordered material with resonant structures patent issued

Etaphase’s US9,720,172 patent issued. “Hyperuniform disordered material with resonant structures” 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.

DARPA Trades uDesign: Type III unums (Posits)

Etaphase Kicks-off DARPA TRADES uDESIGN Program with a presentation by Etaphase Board Member Dr. John Gustafson describing a particularly hardware-friendly version of unum arithmetic known as “Type III unums,” also known as posits. Posits, are designed to efficiently represent data using half as many bits as compared to floats.

US Patent Office issues US9,519,104 to Etaphase

US Patent Office issues US9,519,104 to Etaphase 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.
