“…Volume holographic techniques are of particular interest for their spectral sensitivity and their capacity to achieve spatial as well as temporal modulation of UPB. Recent studies [1][2][3][4] have shown that by choosing proper grating parameters based on the coupled wave theory of Kogelnik [5], it is possible to achieve a large diffraction bandwidth for the readout UPB to be used for frequency-domain pulse shaping, which is applied to the one dimension volume gratings. The input and output boundaries are much larger than the grating thickness.…”

A detailed study of pulse shaping properties in crossed-beam volume gratings is performed. Analytical expressions for the profiles of the transmitted and diffracted beams are obtained based on the modified coupled wave theory. The spatial and spectrum evolutions and the diffraction efficiency of the diffracted pulsed beams are discussed. It is shown that the profiles of diffraction pulses and the total diffraction efficiency are greatly affected by the grating size, recording angle, and refractive-index modulation. The studies indicate that the shaping properties for different geometry parameters of the crossed-beam volume gratings are different. However, this difference can be used for many special pulse shaping applications.

“…Ding [9] have shown both theoretically and experimentally that it is possible in frequency domain to achieve a large enough diffraction bandwidth of VHG for a bandwidth of 100fs pulses mainly by increasing the grating period and decreasing the grating thickness. Recently Wang [10] have studied the pulse shaping properties of a VHG read by an ultrashort pulse considering the combined effects of the grating parameters, the dispersion and optical anisotropy of the media and the polarization state of the incident light. And we also extended the two-dimensional coupled wave theory to study the diffraction of an ultrashort pulsed finite beam by a VHG [11].…”

Volume gratings are of wide interest in many applications because of their properties of high diffraction efficiency, excellent wavelength selectivity and angular selectivity. Ultrashort pulsed laser has many promising applications in the fields such as optical communication, signal and imaging processing. Because of its abundant spectrum and wide bandwidth, the diffraction properties of volume gratings under illumination by ultrashort optical pulse will be different from that of a monochromatic continuous wave. A periodical structure is highly dispersive and such a dispersive property can be used to control the group velocity of light beams. So the spectral properties and dispersive properties of the periodically layered structures such as volume gratings when a linear chirped Gaussian pulse illuminated are very necessary. These properties can be applicable to addressable filter, switching, and controllable optical delay line. In this paper, a detailed study of linear chirped ultrashort pulsed beams diffracted by volume gratings in dispersive media is performed. The group delay characteristics of the diffraction spectrum of the transmitted and reflected volume gratings were studied based on the modified coupled wave theory. The analysis and observation of this paper will be valuable for the designing optical elements based on diffractive structure for the use with linear chirped ultra-short pulsed waves.

“…As a novel class of diffraction elements, a system of MRVHG, which is composed of multiple layers of reflection VHG separated by intermediate layers, is shown in Fig.1. Because of more free parameters, multilayer volume holographic gratings have become an ideal candidate for various promising technological applications such as optical interconnects, pulse shaping and optical filters [4][5][6][7].…”

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.
