“…We denoted it as multi-layer coupled wave theory. Many studies of multilayer VHG have been reported in these years [10][11][12], where a light source is assumed to be continuous wave. Because of its abundant spectrum and high bandwidth, the diffraction properties of MRVHG under illumination by ultrashort pulsed beam (UPB) will be different from that of the monochromatic continuous wave.…”

“…Consequently, the combination of volume holographic elements such as MRVHG and UPB will have enormous potential and novel applications in many practical fields. Very recently, Yan [12][13] first reported the diffraction properties of MVHG under pulsed light, where pulse shaping and diffraction properties of multilayer VHG are discussed in detail. However, the papers only concentrated on the diffraction behavior of an input UPB with Gaussian shape in time.…”

In this paper, the pulse shaping and diffraction properties of multilayer reflection volume holographic gratings under ultrashort pulse with arbitrary shapes in time are investigated using the modified multilayer coupled wave theory. Bragg diffraction of a system of multilayer reflection volume holographic gratings (MRVHG) is derived, and simple analytical expressions for the spectrum and spatial profiles of the transmitted and diffracted beams are obtained. Numerical results of the pulse shaping and diffraction properties of this system are also illustrated for several different temporal shapes.Results show that the temporal shapes of the input pulsed beams have been found to be an important factor in the analyses of the pulse shaping and diffraction properties of MRVHG. The analysis and observations of this paper will be valuable for optimizing the design and for novel applications of optical elements based on multilayer volume gratings.

“…On the other hand, diffraction phenomena in optical communications have a key role in communication network system. Advantages of diffraction devices and gratings make them good candidates for applications in many cases in optical communications including, complex filtering, pulse shaping, processing and precise chromatic dispersion compensation [26][27][28]. So, the study of effects of the temporal coherence on diffraction phenomena is unavoidable in optical communications.…”

We generalize the notion of the Franhoufer diffraction from a single slit and a circular aperture to the case of partially temporal coherent and quasimonochromatic light. The problem is studied analytically and the effect of coherence length on the diffraction pattern is investigated. In this case the far-field distribution of the irradiance depends on the newly introduced parameter η "decoherence parameter" which governs the deviation of the diffraction pattern from the usual one. The η-dependent corrections due to temporal decoherency on the irradiance distribution in the far field is obtained. Numerical study of the effect of decoherence parameter on the Far-field diffraction pattern is performed. In the case of a single slit, there is no noticeable deviation in the central peak, but in the higher orders of diffraction, deviation become apparent. For circular apertures, as long as 1   , the beam decoherency affects the distribution profile and the first order diffraction pattern decreases and by increasing the decoherence parameter, the first order of diffraction pattern gradually disappears.

“…It is shown in [5] that the characteristics of angular selectivity of the structures under study have a series of local maxima, the width of which is determined by the sum width of the whole system (including the intermediate layers), and the envelope of the maxima coincides with the selectivity contour of a single array. In [6], similar structures are called MVHG (Multilayer Volume Holographic Grating) and their diffraction properties are considered as applied to propagation of ultrashort (~50 fs) light pulses. It is shown that the spectral distribution of diffracted light substantially depends on MVHG parameters.…”

Experimental results and analysis of properties of multilayer nonuniform holographic structures formed in photopolymer materials are presented. The theoretical hypotheses is proved that the characteristics of angular selectivity for the considered structures have a set of local maxima, whose number and width are determined by the thicknesses of intermediate layers and deep holograms and that the envelope of the maxima coincides with the selectivity contour of a single holographic array. It is also experimentally shown that hologram nonuniformities substantially distort shapes of selectivity characteristics: they become asymmetric, the local maxima differ in size and the depths of local minima reduce. The modelling results are made similar to experimental data by appropriately choosing the nonuniformity parameters.
