Abstract: A multiwave optical buffer using a loop mirror of the present invention can transmit cells to a preferable node in accordance with electric control, without causing conflicts among the cells, when the cells having various waves reach a single node at the same time on a high-speed network. In order to prevent conflicts among the cells, the multiwave optical buffer using the loop mirror in accordance with the present invention stores cells having low priority and outputs the cells in a preferable time pursuant to the electric phase control, thereby improving efficiency of a high-speed optical communication network.

Abstract: The present invention relates to an apparatus of a high speed optical buffer utilizing a cell pointer so that optical cells of asynchronous transfer mode can be stored and processed at high speed without the restriction of processing time for a high speed network architecture, wherein an internal switch of the apparatus would be controlled by extracting optically the cell pointer indicating starting point by using a high speed optical buffer with terahertz optical asymmetric demultiplex (Terahetz Optical Asymmetric Demultiplexer) in order to avoid a collision of each cell which is transmitted on a same channel especially at the high speed network.

Abstract: An optical asynchronous transfer mode ATM switch for recovering the limitation of processing capacity and performing large capacity of switching is disclosed.
