Progress of terahertz in communication technology

With the development of ultra-fast laser technology and the further recognition of Terahertz(THz) wave and pulse light sources,THz technologies are actively being developed for a variety of applications in security detector,antiterrorism,medical diagnosis and imaging,biotechnology,electron counterwork,information area,which shows that it has a broad foreground.In this paper,it is emphasis on the advantages of THz,which is compared with the infrared and microwave technology,applied to the communication area and the recent progresses of THz in communication technology.Moreover,the key technology of THz communication are discussed.
