1.概述从近十余年通信技术的发展历程可知,电信越来越多地依靠光的配合,电与光共同为现代通信使用。不仅传输是如此,交换(switching)也将如此。光纤的潜在巨大信息容量给人们启示,光在通信中可发挥非常有益的作用,光子与电子交互作用的技术(即光电子技术)应该深入开拓,以至充分实际应用。国外常用photonics,不仅指光子学或光子技术,而是具体地指
1. Overview From the development of communications technologies in the past decade or so, we can see that telecommunications rely more and more on the cooperation of light and electricity and light for the modern communications. Not only this is true of transmission, but also of switching. The potential huge information capacity of optical fibers gives people enlightenment. Light can play a very beneficial role in communication. The technology of photon-electron interaction (that is, optoelectronic technology) should be further developed and fully applied. Commonly used abroad photonics, not only refers to photonics or photon technology, but specifically refers to
