Application and advantage • This device can be used in a communication system. • Better for local network communication systems. • It can be interfaced with fiber optics. • This device is cheaper (presumably on the production line) than fiber optic lasers. • Though lasers are better technology because a lot of time and money has been invested into them, they are still very expensive. • With enough research, SWNT films can be made to have acceptable speeds for metropolitan and local area networks.
