1.前言 自日本应用物理学会首次发表光计算机的研究论文以来已历经十几年的时间,在此期间,每届学会所发表的有关论文逐年增加,到目前平均两年召开一届研讨会。要实现光计算机,对算法和系统结构、系统构成所需的光功能器件、新程序设计技术和方法的调整,无论哪项研究都是必不可少的。 在八十年代,作为运算方法,并行逻缉运算和符号置换逻辑运算,神经网络就已引起人们的关注。在光功能器件领域,多项技术已得到改进,高功能光电元件,高性能衍 1. Preface It has been more than a decade since the Japanese Society of Applied Physics first published a research paper on optical computers. During this period, the relevant papers published by each society have been increasing year by year, and at present there is an average of two seminars a year. In order to realize the optical computer, no matter which research is indispensable to the adjustment of the algorithm and the system structure, the optical functional devices needed for the system constitution and the new programming techniques and methods. In the 1980s, as a computing method, parallel logic operations and symbol replacement logic operations, neural networks have attracted people’s attention. In the field of optical functional devices, a number of technologies have been improved, high-performance optoelectronic components, high performance
