Monolithically formed curved polymer diffractive optical waveguides for augmented reality displays

We have fabricated waveguides in a high index, UV curable polymer resin (nd>1.7) with a 50 degree diagonal field of view and a 1.3 diopter focal length for augmented reality applications. The polymer eyepiece is more than 50% lighter than a comparable glass eyepiece with improved ruggedization and lower cost. The curve of the waveguide eliminates the need for additional refractive elements to set the virtual content depth plane, further reducing weight and expense. These waveguides leverage the knowledge and infrastructure from Magic Leap devices, expanding market opportunities for reduced field-of-view use cases.
