| Abstract: | Laser communication, terahertz communication and quantum communication are prospected in space information transmission and distribution systems. Laser communication links can be used in the construction of the backbone of the future space networking. The quantum links adding to the laser links can greatly increase the communication secrecy. Terahertz links can be used in communications between nodes in satellite constellation. They offer large bandwidth and flexible net connecting. These novel techniques can play an important role in future space information transmission and distribution systems. |
