From a materials perspective optical fibers are victims of their own success. The advent of the laser, 50 yr ago, coupled with an insatiable demand for information enabled by light‐based communications, ushered in a golden age of glass science and engineering. It is somewhat ironic that the staggering ubiquity of information today, which is carried globally and almost instantaneously via optical fibers, is enabled largely by one material—silica—into which only a few components are added. The richness of the Periodic Table has largely been forgotten. The purpose of this study was to rethink the materials that can be used to make commercially relevant optical fibers and describe the extraordinary properties, with stimulated Brillouin scattering being the primary exemplar, of fibers made from otherwise ordinary materials. In particular, this study focuses on the use of the molten core approach to optical fiber fabrication and the novel yet practical fibers that can be produced. This study is purposely provocative and aims to reassert the centrality (and simplicity and beauty) of glass science as the best approach to meet future challenges for high‐performance optical fibers. 相似文献

1999版TEMA标准与1988版TEMA(含1990,1991修订版,以下简称1988版TEMA)相比,在实用范围和内容上均发生了很大的变化,变得更加丰富了。鉴于TEMA标准是国内外比较公认、流行性很广的换热器工程设计标准,及时了解和掌握最新版TEMA的变化便显得十分必要。 相似文献
