<P>PROBLEM TO BE SOLVED: To provide a very high speed optical memory method and apparatus using a bistable semiconductor laser capable of controlling each bit and reading out information at the necessary timing. <P>SOLUTION: The very high speed optical memory apparatus using bistable semiconductor laser includes an array 5 having a plurality of bistable semiconductor lasers performing AND gate operation and memory operation, optical signal write means for writing an optical signal to the array 5, and optical signal read out means for reading out the optical signal written to the array 5. The apparatus is an entirely-optical type not converting the optical signal into an electric signal, records a time-series optical signal to the bistable semiconductor laser bit by bit and reads out the recorded signal as a time-series signal at a necessary timing. Moreover, it is possible to transfer a recorded signal from a bistable semiconductor laser to another bistable semiconductor laser and record it there. <P>COPYRIGHT: (C)2004,JPO |
