七十年代末、八十年代初,纤维光学对长距离通信作出了十分引人注目的贡献,它推动了人们研究利用光学方法解决最高级次上的互连问题,即处理器和处理器间的互连。早在1979年,Cathey和Smith提出了一种用于计算机内部的自由空间光学并行数据总线;1981年Tajima、Okada和Tamura提出研制用于多处 The late 1970s and early 1980s, fiber optics made a very compelling contribution to long-distance communications, it promoted the study of the use of optical methods to solve the highest level of interconnection between the processor and the processor The interconnection. As early as 1979, Cathey and Smith proposed a free-space optical parallel data bus for use in computers. In 1981, Tajima, Okada and Tamura proposed the development of a parallel-
