description An optical device for controlling light in an augmented reality display is provided. The optical device comprises a waveguide and a diffractive optical element configured to couple light into the waveguide. The diffractive optical element comprises an array of structured grating elements, the structured grating elements being arranged based on a repeating unit cell, wherein each unit cell comprises at least two grating elements defining an irregular grating structure such that the diffractive optical element produces an asymmetrical diffraction response. A method of manufacturing the optical device is also provided.
