澳大利亚的一位物理学家研制出一种二极管激光器、其复合材料之间使用超薄型分隔片。墨尔本澳大利亚电信学会的彼得·凯梅尼介绍说,一个拇指甲大小的微小基片上,将安置一万个他那种激光器。这种比一颗盐粒还细微的激光器,垂直于其表面发射光束,其方式同于美国的研究者上个月(《技术》,8月12日)公布的袖珍激光器。通过将激光器作垂直而不是象传统那样作水平安装,制造者就可获得更致密的光电子电路设计。发自一大阵列激光器的相干光束使得设计者可利用更强大的光源来驱动光纤电缆并 A physicist in Australia developed a diode laser with thin separators between the composite materials. Peter Kemeney of the Melbourne Telecommunications Society of Australia said that 10,000 tiny lasers will be placed on a tiny thumbnail-sized substrate. The laser, which is more subtle than a salt particle, emits light perpendicular to its surface in much the same way as the pocket-length laser released by researchers in the United States last month (Technology, August 12). By verticaling the laser rather than horizontally as is conventional, manufacturers can obtain denser opto-electronic circuit designs. Coherent beams from a large array of lasers allow designers to use more powerful light sources to drive fiber optic cables
