Ca1 光电技术与信息工程——兼论光电技术的发展趋向张肇群(华中工学院无线电系)电子学的历程是“频率高频化”的历程。人工发射的电波,据理论推算,其波长上限也不过是1mm,微波通信已到了尽头。根据量子效应振荡原理,出现了比微波频率高1000倍的激光,频率界限被打破,载波频率扩大了1000倍,这给“频率高频化”带来了希望。随着设备性能的提高,电子系统的元件个数迅猛增加。因为电子元件都是作为单一的物理效应原件来应用的,这就必然产生由物理定
Ca1 Optoelectronic Technology and Information Engineering - Also on the Development Trend of Optoelectronic Technology Zhang Zhaoqun (Department of Radio, Huazhong University of Science and Technology) The course of electronics is the course of “high frequency of frequency”. Artificial radio waves, according to the theory of projection, the wavelength limit is only 1mm, microwave communication has come to an end. According to the principle of quantum effect oscillation, a laser 1000 times higher than the microwave frequency appears, the frequency limit is broken, and the carrier frequency is expanded 1000 times, which brings the hope of “frequency high frequency”. As device performance increases, the number of electronic system components increases rapidly. Because the electronic components are used as a single physical effects of the original application, which inevitably produced by the physical
