ETAPHASE

Our Technology

Etaphase technology involves new structural architectures of materials. Our patented approaches to meta-materials allow for designs optimally suited to target applications.  Our core technologies include ‘quasicrystal’ architectures (the subject of 2011’s Nobel Prize in Chemistry) and ‘hyper-uniform disordered structures’ (‘HUDS’).

HUDS are ‘semiconductors for light’ that were discovered at Princeton by the Etaphase founding scientific team. HUDS materials present the unexpected ability to provide a complete bandgap in an isotropic structure, a property previously though to be impossible to achieve.  The isotropy means that input and output signals are the same in all directions, a feature that enables more flexible and more compact designs of photonic devices.  These bandgaps can be precisely tuned, and can be static or dynamically alterable.  HUDS devices can operate across the entire electromagnetic spectrum.  A significant additional feature of HUDS materials is that they are fully isotropic.  This means that input and output is uniform from any angle.

HUDS architectures for photonic integrated circuits (PICs) provide new non-Cartesian layout options for compact, photonic band gap structures, improved temperature sensitivity, isotropic coupling, and dynamically-tunable performance.  HUDS devices are based on ‘semiconductors of light’ which are isotropic.
