Wave-optical design and its relation to Diffractive Optics
Frontiers in Optics 2004 Laser Science XXII Diffractive Optics and Micro-Optics Optical Fabrication and Testing, 2004Co-Authors: Frank WyrowskiAbstract:Actually optical engineering experiences a generalization. Physical Optics modelling and design methods enrich geometric Optics based techniques which still dominate the design of optical systems. The role of Diffractive Optics in this process is discussed.

v Diffractive Optics electromagnetic approach
Progress in Optics, 2000Co-Authors: Jari Turunen, Markku Kuittinen, Frank WyrowskiAbstract:Publisher Summary This chapter discusses the electromagnetic approach for the Diffractive Optics. The chapter focuses on the domain of Diffractive Optics in which rigorous electromagnetic theory is necessary or useful. The chapter describes one approach to rigorous analysis of gratings. The chapter discusses the linear gratings, which employ the first and zeroth diffraction orders. Diffractive elements obtained by modulating these gratings are also discussed in the chapter.. The chapter describes the linear diffraction gratings, which produce two transmitted or reflected orders, the zeroth and (minus) first orders. Together with improved fabrication technology, the use of rigorous theory has pushed Diffractive Optics beyond the limitations of the paraxial approximation, and therefore significantly broadened its applicability in optical engineering.

Diffractive Optics in physical-Optics system design
18th Congress of the International Commission for Optics, 1999Co-Authors: Frank Wyrowski, Jari TurunenAbstract:The use of microstructured interfaces to realize optical functions is the subject of Diffractive Optics. In this talk we discuss the role of Diffractive Optics in optical engineering. To this end optical design is based on a physical-Optics model. It is established that microstructures can present alternative ways to realize optical functions and that they can be the ultimate choice to obtain a desired optical effect.

Polarization dependent focusing lens by use of quantized Pancharatnam-Berry phase Diffractive Optics
Applied Physics Letters, 2003Co-Authors: Erez Hasman, Gabriel Biener, Vladimir Kleiner, Avi NivAbstract:Quantized Pancharatnam–Berry phase Diffractive Optics using computer-generated space-variant subwavelength dielectricgrating is presented. The formation of the geometrical phase is done by discrete orientation of the local subwavelength grating. We discuss a theoretical analysis and experimentally demonstrate a quantized geometrical blazed phase of polarizationdiffraction grating, as well as polarization dependent focusing lens for infrared radiation at wavelength 10.6 μm.
