在传统计算机芯片上，电信号沿着金属线在集成电路上排列的各种信息处理电子元件（如晶体管）之间传输。高性能计算的目标之一是从电连接转向光连接。原因很简单：光传播速度非常快，而且在途中可能没有任何损耗。开发此类技术将需要开发精密的“光导管系统”，以便能够在芯片上传输（或者更好的是，产生）、运送和调制光子流。看起来所有这些开发在不久的将来都很有可能实现。纳米制造技术的最新进展已经生产出了一系列令人印象深刻的超小型光学设备，这些设备可以安装在单个计算机芯片上。
On a traditional computer chip, electric signals travel along metallic wires between various informationprocessing electronic components such as transistors arranged on an integrated circuit. One of the goals of highperformance computing is to move away from electric connections to optical connections. The reason is simple: light travels very fast and potentially without any losses en route. Developing such technologies will require developing sophisticated “optical plumbing” capable of delivering (or, better yet, producing), transporting, and modulating streams of photons on a chip. It is increasingly looking like all these developments are not too far in the future. Recent advances in nanofabrication have already produced an impressive range of ultracompact optical devices that can fit on a single computer chip.
