Abstract

See full text

An optical device and an eyeware apparatus comprising the optical device are disclosed. The optical device comprises a diffraction grating configured to diffract an incident light of a given wavelength on said optical device, said diffraction grating having a grating pitch above said given wavelength and being configured to diffract said incident light at a diffraction order having an absolute value equal to or greater than 2, wherein the optical device comprises an optical waveguide configured for guiding said light diffracted at a diffraction order having an absolute value equal to or greater than 2. The diffraction grating comprises a substrate of a first dielectric material with refractive index n3 and at least one second dielectric material with refractive index n2 deposited on said substrate, where n32 or n3=n2.
