中文摘要 | 1963年P. J. van Heerden研究體積全像術,首次提出以體積來儲存資訊,將具有極大的潛力以提升資料容量與存取速度。因此,在找尋未來“極限”的資訊儲存技術時,體積全像技術往往被視為一個重要的指標。1990年代末期,電子器件技術的蓬勃發展,帶動此領域的快速發展,建立完整的學理理論與工程技術,展示單一全像碟片容量超過10TB、讀取速度10Gb/s的可行性,但是,其中懸而未解的一個關鍵問題是儲存媒體。在這篇文章裡,我們將討論體積全像光資訊儲存的基本原理,分析研製體積全像資訊儲存媒體所需的材料系統參數,並據以討論研製摻雜式的體積全像高分子記錄材料PQ/PMMA作為資訊儲存應用的各項特性,同時以實驗展示其資訊儲存特性。 |
英文摘要 | In 1963, by studying properties of volume hologram, P. J. van Heerden mathematically demonstrated that storing optical information in solids has huge potentials of capacity and data rate. In the search for future ”ultra” storage technologies volume holography is therefore considered as a potential candidate. In late 1990s, one can observe intensified research activities concerning various aspects of this field, including the development and theoretical analysis of powerful multiplexing schemes, the availability of suitable recording materials and affordable lasers, modulators, and detectors. Experiments demonstrated the possibilities of 10 TB capacity in a disk and 10 Gb/s data rate. However, for pursuing the commercialization of holographic memories, one of these aspects, suitable volume holographic storage materials, is still an open question. In this paper, we review the progress and challenges of volume holographic data storage and present a methodology for material evaluation. A strategy by using doped photopolymers, PQ/PMMA to fulfill most of material requirements will be proposed and demonstrated. |
