项目摘要

This research aims to develop an optical network processor for an optoelectronic parallel computing system based on a parallel computing architecture called OAL-NC (optical array logic network computing). The obtained results are as follows :1. For design of the discrete correlator for the OAL-NC network processor, an effective method based on automatic-lens design and substitution of commercially available lenses has been developed. With the method, a small-distortion optical system has been designed consisting of 6 lenses.2. The designed optical system has been constructed and its performance were verified. Due to broad emission of the light emitting diodes, optical power efficiency was only 0.0005%, which suggests requirement of redesign of the system.3. For the prism array of the discrete optical correlator, a fabrication technique using photo-sensitive polymer with a Twyman-Green interferometer has been developed. The attained precision was 2 degree for the top angle.4. Operational characteristics of the discrete correlator has been evaluated in the OAL-NC experimental system (16 x 16 pixel system). XOR logic was successfully executed in the context of optical array logic.5. For integration of optical systems, a discrete correlation module has been constructed using photo-sensitive polymer. The optical system is composed of two lenses with 15mm diameter and 21.8mm focal length and a prims array. Optical resolution of the module is 16 lp/mm.

本研究旨在开发一种用于光电并行计算系统的光网络处理器，该系统基于称为OAL-NC（光阵列逻辑网络计算）的并行计算架构。所得结果如下： 1．为了设计 OAL-NC 网络处理器的离散相关器，开发了一种基于自动透镜设计和商用透镜替代的有效方法。利用该方法设计了由6片透镜组成的小畸变光学系统。 2．所设计的光学系统已经搭建完毕，并对其性能进行了验证。由于发光二极管的宽发射，光功率效率仅为0.0005%，这表明需要重新设计系统。3．对于分立光学相关器的棱镜阵列，已经开发出一种使用光敏聚合物和泰曼-格林干涉仪的制造技术。顶角精度达到2度。 4．离散相关器的操作特性已在 OAL-NC 实验系统（16 x 16 像素系统）中进行了评估。异或逻辑在光阵列逻辑的背景下成功执行。5．为了集成光学系统，使用光敏聚合物构建了离散相关模块。光学系统由两个直径15mm、焦距21.8mm的透镜和棱镜阵列组成。模块的光学分辨率为 16 lp/mm。
