Trends of Research on Microwaves/Optics in Japan

Abstract

Recent growing demand, both in quantity and quality, for communications triggers the communication technology to incorporate and integrate media of two different genre, i.e., microwaves and lightwaves (optics). Devices and systems utilizing both microwave and optical technologies are investigated. Recent research and development in this field are reviewed in this paper. Characteristics of radio and optical fibers are reviewed, and subcarrier multiplexing systems and opto-microwave devices are described.
