当电子线路达到其最小极限时 ,计算机速度就成为一个难题。以每月几乎 15%速率扩张的互联网迅速增长将很快要求比电子线路更快的速度和更宽的带宽。虽然全光计算机的实现仍需时日 ,马歇尔空间飞行中心的科学家正着手研究用光来加速计算和增加数据带宽这种更快计算机的需求。科 When the electronic circuit reaches its minimum limit, computer speed becomes a challenge. The rapid growth of the Internet, which is expanding at a rate of almost 15% per month, will soon demand faster speeds and wider bandwidth than electronic circuits. Although the realization of all-optical computers will take time, scientists at the Marshall Space Flight Center are investigating the need for faster computers that use light to speed up calculations and increase data bandwidth.
