Femtosecond Optical Encoding for High-Speed Fiber Communications: Technology and Systems Studies

9626967韦纳这个项目的目的是实验测试的新型超短脉冲码分多址（CDMA）光纤通信系统。 这些系统通过飞秒光编码和解码技术实现，该技术使用无源并行调制方案来实现太比特/秒的有效串行调制速率。 通过将不同的、干扰最小的光码序列分配给不同的用户对，在这样的系统中容纳多个用户。 光CDMA的一个独特属性是使用光处理，它可以绕过电子瓶颈，并有可能直接在光域中实现某些网络操作，如寻址和安全性，这些操作传统上是以电子方式执行的。 CDMA方法的影响可能集中在相对短距离上的高性能应用，例如超级计算机互连。 ***

9626967 Weiner This project aims at experimental tests of novel ultrashort pulse code-division, multiple-access (CDMA) fiber communications systems. These systems are enabled by a femtosecond optical encoding and decoding technology, which uses a passive parallel modulation scheme to achieve Terabit/sec effective serial modulation rates. Multiple users are accommodated in such a system by assigning different, minimally interfering optical code sequences to different subscriber pairs. A unique attribute of optical CDMA is the use of optical processing, which can circumvent electronics bottlenecks and which potentially can implement directly in the optical domain certain network operations, such as addressing and security, which traditionally have been performed electronically. The impact of the CDMA approach is likely to focus on high performance applications such as supercomputer interconnects, over relatively short distances. ***
