Analysis and applications of optical diffraction by gratings
Thomas K. Gaylord,M. G. Moharam +1 more
TL;DR: In this article, an exact formulation of the grating diffraction problem without approximations is presented, using a series of fundamental assumptions, which reduces to the various existing approximate theories in the appropriate limits.

The theory, design, and applications of surface acoustic wave Fourier-transform processors
TL;DR: Theoretical results show how specific arrangements of physically realizable SAW chirp filters permit Fourier transformation of both baseband and IF input signals, and the operation of SAW Fourier-transform processors, with separate real- and imaginary-baseband inputs, highlights their use as wide-band "FFT-type" processors.

Calculation and experimental verification of two-dimensional focusing grating couplers
D. Heitmann,C. Ortiz +1 more
TL;DR: In this paper, a ray tracing method has been performed to calculate the focus spot size of two-dimensional focusing grating couplers that are produced by holographic interferometry of freely propagating wavefronts.

Optical volume holography
TL;DR: In this article, the authors describe various theoretical techniques which have been used to model the reconstruction process in a volume hologram, and an historical view of volume holography, from its invention by Denisyuk in 1962, and a detailed discussion of hologram grating formation in the various photosensitive materials now available.

Planar waveguide bragg lens and its utilization
TL;DR: In this article, a planar waveguide Bragg lens with a greater acceptance angle was proposed. But the acceptance angle is characterized by several grating structures being arranged in series and having an inclination towards one another for varying angles of incidence.
