Optical fiber and fiber taper are used for reference waves in writing and reading volume holograms. The object wave interferes with the speckle pattern reference wave coming from fiber tip in the holographic medium to make a volume hologram. The spatial selectivity of the volume hologram is improved by the proposed scheme. Both experimental results and theoretical analysis are discussed.
High-density and compact volume holographic memory is interfaced with electronic processors. Writing and reading are performed in parallel through high-degree wavelength and angular multiplexings. High-bandwidth of optical fibers are used to transfer data between memories and processors.
A general-purpose electronic computer is introduced to run a variety of parallel algorithms efficiently. Various levels of modular structures function independently and maximum flexibility results. Furthermore, the integrated modular components are all connected optically to each other to reduce the communication time dramatically. Computational power of the new computer is derived and the capability of handling intensive computation and complex information processing in real time is proved.
