Stratified volume diffractive optical elements as high-efficiency gratings [PDF]
Journal of the Optical Society of America A: Optics and Image Science, and Vision, 1999 We propose stratified volume diffractive optical elements as a new type of diffractive optical element that is capable of functioning as a high-efficiency grating in applications with requirements not suited to traditional holographic or diffractive ...

On a diffractive optical element
2004 International Semiconductor Conference. CAS 2004 Proceedings (IEEE Cat. No.04TH8748), 2005A diffractive optical element (DOE) aimed to reshape a Gaussian laser beam into a straight uniform light line is presented. Theory, the design procedure and technology are briefly described. Moreover a binary reflective DOE using a technology based on UV lithography and wet etching have been manufactured. Despite of a lot of fabrication errors, the DOE

Diffractive optical elements that can be used to manipulate the amplitude, phase, and polarization of a wavefront in very complex ways are treated. Optical components whose feature size is larger than one wavelength, about equal to one wavelength, and smaller than one wavelength are considered.

Elements of diffractive optics
SPIE Proceedings, 1999Diffractive optics makes use of diffraction of light to design otpical elements and systems, which serve for imaging visual objects and transforming coherent optical beams. A diffractive structure can be computed and the pattern written using focused laser or electron beams. Phase nature of diffraction pattern is preferred.

Multilayer technology for diffractive optical elements
Applied Optics, 1996The proposed multilayer technology makes it possible to approximate a continuous phase distribution by discrete phase steps. Compared with binary techniques, a higher diffraction efficiency can be achieved. In most known processes a bulk substrate is used and etched directly; therefore it is difficult to control the height of the phase steps.

Diffractive optical elements for optical identification
Applied Optics, 2015We present the design and fabrication of diffractive optical elements for optical identification purposes. Two methods for optical identification are discussed. In this feasibility study, approaches using one and two binary reflective diffraction gratings are demonstrated.
