Volumes Analysis of diffraction properties of stratified volume holographic grating in anisotropic media

Zhijuan Hu Dean Liu aiming Yan Xin Wan Iiren Liu

Stratified volume holographic optical elements (SVHOE's) comprise a recently proposed class of novel diffraction structure, it's unique angular selectivity of the SVHOE's Bragg diffraction process have more promising applications. The previous study of SVHOE's are mainly based on isotropic materials, in this paper we study the diffraction properties of holographic gratings in anisotropic media separated by buffer layers using the method of Coupled wave theory. It is shown that the diffraction efficiency of such system also exist the uniform periodic angular sensitivity, in addition the dependence of the periodic SVHOE angular sensitivity on number of layers and total SVHOE thickness have been discussed.

The effect of deposition temperature on films" microstructures and optical properties was investigated. The sample deposited at 500℃ exhibits not only a pure perovskite phase, highly (110)-preferred orientation, and dense and crack-free morphology, but also the largest average remnant polarization of 17.2 μC/cm2 among all investigated films. With Cauchy model the refractive indices and extinction coefficients for these specimens have been obtained by fitting experimental reflectance spectra. At a wavelength of 633 nm, the value of refractive index is 2.41 was obtained for the thin films deposited at 500 ℃. In addition, optical band gaps of the films are in the range of 2.97–3.22 eV. A preliminary discussion has been carried out on the difference in the optical properties of these films. 参考文献相似文献引证文献

High speed and low side lobe optical phased array steering by phase correction technique

Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE (2013)

Yadong Jin Aimin Yan Zhijuan Hu Zhenyu Zhao Wangzhou Shi

Laser beam scanners are important optical elements with a large variety of applications in the measurement techniques, optical communications, laser imaging ladar, etc. Agile beam steering of optical radiation using phased arrays offers significant advantages, such as weight, stability and power requirements over conventional beam steering systems. There are several kinds of optical phased array technology to be developed, such as Lithium tantalite phase shifters, lithium niobate electro-optic prism deflectors, and liquid crystal and ferroelectric liquid crystal phase modulations. However, one of the major drawbacks of these approaches is low light efficiencies because of the side lobes in far-field pattern of the steering beam. In this paper, a new low side lobe optical beam steering technique using phase correction technique is proposed. A stable and fast single-lobed far-field pattern in steering beam can be obtained from the optical phased array with a phase plate by optima design. It can result in a substantially increased light efficiency and beam quality. The quantitative calculation results of typical optical phased array are demonstrated. The low side lobe optical beam steering technology of optical phased array will benefit many practical applications such as laser ladar, laser communications and high resolution displays.

Xin Wang Liren Liu Aimin Yan Zhu Luan Zhijuan Hu

In this paper, the theory model in which both the two-center material equations and two-dimensional two-wave coupled equations were solved jointly based on two-center holographic recording method is presented to analysis the dynamic formation of the crossed-beam photorefractive gratings in two doped LiNbO₃ crystals. The influence of the light intensity on the basic holographic properties of the crossed-beam photorefractive gratings in LiNbO₃:Fe:Mn crystals is explored. The numerical simulation results are presented. The investigation yields quantitative predictions of the expected behavior of the dynamics of these gratings, which can be useful for the design of finite boundary photorefractive holographic optical elements.

Study of wavelength-dependent diffraction properties of photorefractive volume holographic lenses for optical beams conversion

Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE (2007)

Zhijuan Hu Aimin Yan Dean Liu Liren Liu

A new type of photorefractive volume holographic lenses for converting a plane wave to a lateral-spread spherical wave with different wavelength has been suggested, which are recorded at 632.8nm wavelength and reconstructed at 800nm wavelength. Using the coupled-wave theory, the wave-front conversion by photorefractive volume holographic lenses between spherical and plane waves is studied. The off-Bragg parameter values of the holographic lenses in the reconstruction process are analyzed. The dependence of diffraction efficiencies on the focal length of recording spherical wave and the geometric sizes of the photorefractive holographic lenses are discussed in detail. In addition the intensity distributions of the diffracted beam are analyzed also.
