Micro- and Diffractive Optical Elements
2018With the rapid development of modern optics and optoelectronic technology, optoelectronic components have also changed greatly. Optical elements are not only limited in refractive lenses, prisms, and mirrors. New optical components such as micro-lens arrays, holographic lenses, and diffractive elements are also used in various optoelectronic devices ...

Diffractive components: holographic optical elements
1993Besides refractive and reflective components, planar diffractive optical elements are promising for free space optical interconnects. The content of this chapter is focused on holographic optical elements (HOEs), which are diffractive elements fabricated by recording the interference pattern of an object and a reference wave in a photosensitive ...

Fabrication of Diffractive Optical Elements
2017In earlier chapters, the design and analysis of simple and multifunctional DOEs using different techniques are presented. In this chapter, pre-fabrication techniques such as designing the lithography files, etc., and fabrication techniques with basic fabrication recipes are presented. The fabrication of micro-optical elements using photolithography has

Diffractive optical elements for optoelectronics
Diffractive Optics: Design, Fabrication, and Applications, 1992Diffractive optical elements (DOEs) rely on the deflection of light waves by diffraction on microstructures rather than on refraction by smooth surfaces. They are well-suited for applications involving monochromatic light and lasers: They are flexible in design (synthetic holograms are designed by CAD), it is possible to fabricate array-optics (several

Making a Diffractive Optical Element
2009In previous chapters we considered the fundamental theories of diffraction and a number of design approaches for diffractive optical elements. However, before a diffractive optical element can be built, a number of additional questions must be addressed. For example: - How is the design in a computer "transformed" into a physical component?

Multifocus optical pickup with diffractive optical elements
SPIE Proceedings, 1999A novel optical pickup based on DOEs is proposed and first optical key elements are designed and fabricated. The DOE- pickup enables multi-focus imaging and speeds up the data transfer rate. Parallel reading of many tracks and two or more superimposed memory layers is possible.

Diffractive optical elements as raster-image generators
Applied Optics, 2001The use of diffractive optical elements (DOEs) to generate complex raster images for a primarily artistic purpose is dealt with. Aspects of human vision that are relevant for the design of such elements are discussed. A design method based on an iterative Fourier transform algorithm and extended with elements from the direct-binary-search and the ...
