“…In recent decades, various media have been studied and developed for use in applications such as, holographic optical elements, holographic data storage [1][2][3][4][5][6][7][8][9][10][11][12], and hybrid photonic circuits [13][14][15][16]. Photopolymers are one of the most promising media of choice for such applications due to their versatility, ease of use, potential to be cast into thick layers having, environmental stability and self-processing ability.…”

Abstract:The development of suitable recording media for applications such as holographic optical elements and holographic data storage are of significant research and commercial interest. In this paper, a photopolymer material developed by Bayer MaterialScience is examined using various optical techniques and then characterised using the Non-local Photopolymerization Driven Diffusion model. This material demonstrates the capabilities of a new class of photopolymer offering high index modulation, full colour recording, high light sensitivity and environmental stability. One key result of this study is the material's high spatial frequency resolution, indicating a very low non-local effect, thus qualifying it as a very good storage medium. ©2011 Optical Society of America References and links1.

“…The diffracted signal also directly reflects the spatial distribution of the nonlinear material in the focal region. 13) In conventional uniform nonlinear optical media, slowly varying amplitude (SVA) approximation can be applied to the coupled wave equation for wave mixing. In contrast the SVA approximation cannot be applied to a sample with a nanostructure.…”

We demonstrate cell imaging with a new confocal nonlinear optical microscope using a low-power cw laser. The confocal nonlinear optical microscope, employing degenerate four-wave mixing geometry, can detect the fine structure of submicron objects with nanoscale contents such as biological cells. The optical signal, which is given by the third-order susceptibility tensor, is confined to the focal region of the focusing incident beam, because the absorption of the object is dependent on the third power of the excitation laser intensity. We have observed a thylakoid membrane in a chloroplast by scanning the tensor element inside.

“…The self-developing of most materials require only some simple post-processing steps, for example an exposure to light or heat treatment. Therefore, this will eliminate the need for wet chemical development, because these photopolymers are suitable for holographic and waveguides applications [24,25,26,27], and also holographic data storage [22,28,29,30,31,32,33,34,35,36,37,38].…”

Abstract:Photopolymer materials have received a great deal of attention because they are inexpensive, self-processing materials that are extremely versatile, offering many advantages over more traditional materials. To achieve their full potential, there is significant value in understanding the photophysical and photochemical processes taking place within such materials. This paper includes a brief review of recent attempts to more fully understand what is needed to optimize the performance of photopolymer materials for Holographic Data Storage (HDS) and Self-Written Waveguides (SWWs) applications. Specifically, we aim to discuss the evolution of our understanding of what takes place inside these materials and what happens during photopolymerization process, with the objective of further improving the performance of such materials. Starting with a review of the photosensitizer absorptivity, a dye model combining the associated electromagnetics and photochemical kinetics is presented. Thereafter, the optimization of photopolymer materials for HDS and SWWs applications is reviewed. It is clear that many promising materials are being developed for the next generation optical applications media.
