  • Transfer of optical element patterns on a same side of a substrate already having a feature thereon
    Publication number: 20090225422
    Abstract: A passive optical element is transferred into a substrate already having features with a vertical dimension thereon. The features may be another passive optical element, an active optical element, a dichroic layer, a dielectric layer, alignment features, metal portions. A protective layer is provided over the feature during the transfer of the optical element. One or more of these processes may be performed on a wafer level.

  • Reduced loss high efficiency diffractive and associated methods
    Publication number: 20090009869
    Abstract: A sub-wavelength anti-reflective diffractive structure is incorporated with a base diffractive structure having a small period to form a high efficiency diffractive structure. In the high efficiency diffractive structure, the anti-reflective structure and/or the base diffractive structure are altered from their ideal solo structure to provide both the desired performance and minimize reflections.
