Applied Optics, 1997
Diffractive optical elements with blazed profiles can, in theory, have 100% relative efficiency. We review several methods for making such elements and compare their advantages and limitations. Our emphasis is on processes to produce elements other than those with approximate, stepped surfaces, such as binary optical elements.

Diffractive optics: an introduction to the feature
Applied Optics, 1993This feature of Applied Optics contains 16 papers on the design, fabrication, analysis, and applications of diffractive optics. Most of the papers originated from the first Optical Society of America topical meeting on diffractive optics that was held 13-15 April 1992 in New Orleans, Louisiana.

Developing diffractive optics for optical computing
IEEE Micro, 1994Diffractive optical elements easily handle tasks such as the generation of uniform arrays of beams, beam steering and focusing, and aberration correction that conventional optics alone often find difficult or impossible. Here we review the design, fabrication, and performance of DOEs for use as free-space interconnection elements in optical-computing ...

Extending Depth-of-Field of Arbitrary Diffractive Optics with Needle-Shaped Beam Modulation
ACS PhotonicsThis study presents a phase-modulation technique capable of flexibly extending the depth-of-field (DOF) of any diffraction pattern. This method, deep diffractive optics (DDO), involves integrating a needle-shaped beam phase modulator with a conventional ...

Digital diffractive optical memories
Proceedings of Third International Conference on Electronics, Circuits, and Systems, 2002We show that the possibility of storing more informations within a decreased volume is now opened. This is due mainly to the recording material we have used which is an improved polypeptide of dichromated gelatin. The input digital information is recorded and a diffractive digital image is reconstructed. The percentage of pixels error detection is less

Diffraction gratings and optical aberrations
Applied Optics, 1984The effects introduced by a plane diffraction grating on the diffracted wave front when a quasi-plane beam incides on it are calculated. Effects not previously discussed appear.

Weighted optical diffraction gratings
Applied Optics, 1988This paper describes the behavior of optical diffraction gratings which have been weighted in various ways analogous to those used in surface acoustic wave devices. It is shown experimentally and theoretically that a wide variety of 2-D responses can be achieved by these means.

Diffractive–reflective optical interconnects
Applied Optics, 1988We have demonstrated the feasibility of diffractive-reflective optical interconnects. These interconnects consist of a sandwich of a holographic plane and a reflective plane. Various possibilities like beam relaying, connection switching, and broadcasting are discussed.
