The optical time division switch scheme using optical scanning was proposed in this paper. Quick switching can be realized by the optical element and optical system based on the proposed scheme. The modulation velocity of the proposed scheme can be of the order of nanosecond, which is quick enough for the next generation of optical communication. This scheme will be a key technology in the optical network. The principle of the scheme is studied. The structure of the scheme is proposed and the performance is analyzed.
