光脑是新世纪之初的必然产物,正如电脑是以电子作为主要的信息载体一样,光脑是以光子作为主要信息载体的,光脑(optical computing)的全称是光子计算机。目前在硬件和软件的两个方面的研究非常活跃。它可以完成高难度的并联运算,其工作原理基本上和电脑一样,不同的是用光子代替了电子,用光互连代替了电子导线互连,用光运算代替了电运算。 Optical brain is an inevitable outcome of the beginning of the new century. Just as computers are electronic information carriers, optical brain uses photons as the main carrier of information. The whole name of optical computing is photon computer. The current research in both hardware and software is very active. It can be difficult to complete the parallel operation, and its working principle is basically the same as the computer, the difference is the use of photons instead of electrons, optical interconnects instead of electronic wire interconnection, optical computing instead of computing.
