Embodiment Construction

[0016] overview

[0017] Currently implemented diffractive optical element (DOE) lenses form their DOE (e.g., diffractive surfaces, which contain microstructures (e.g., fine surface structures, micron and submicron step structures)) at the front side of the die or corner glass . The DOEs of these currently implemented DOE lenses are highly susceptible to contamination and surface defects through exposure to their application environment and / or their manufacturing environment.

[0018] Described herein are methods for fabricating planar DOE lenses that are less sensitive to environmental factors than currently implemented DOE lenses.

[0019] example implementation

[0020] figure 1 ( figure 1 ) is a conceptual layout of a planar diffractive optical element (DOE) lens according to an exemplary embodiment of the present disclosure. In an embodiment, planar DOE lens 100 includes a substrate 102 . In an embodiment, substrate 102 is a light transmissive (eg, transparent) ...

Abstract

Planar diffractive optical element (DOE) lenses are described herein. Planar DOE lenses contain a substrate. The planar DOE lens also includes a first layer formed on the substrate. The planar DOE lens also includes a diffractive optical element formed on the first layer. The planar DOE lens also includes a second layer formed on the first layer. A second layer is also formed on the diffractive optical element. The second layer surrounds the diffractive optical element between the first layer and the second layer. The second layer contains planar surfaces.

Description

[0001] Cross References to Related Applications [0002] This application claims priority benefit to U.S. Provisional Application No. 61 / 778708, entitled "Planar Diffractive Optical Element Lens and Method for Producing Same," filed March 13, 2013, which is hereby incorporated by reference in its entirety. Background technique [0003] Diffractive optics are used in many applications such as optical storage, processing, sensing and communication. Diffractive optical elements (DOEs) are thin phase elements that operate by means of interference and diffraction to produce arbitrary distributions of light or to aid design in optical systems. Design the DOE for application with lasers (eg, high power lasers). In addition, DOE is used for wave shaping (waveshaping). For example, DOEs can be used as multi-spot beam splitters in beam shaping and beam profile modification. DOEs are capable of transforming a single laser beam into light patterns of various simple or complex structure...
