Regeneration of optical signals by fiber logic elements operating through stimulated Raman scattering and development of fiber optic memory

Vladimir I. Belotitskii, Eugenii A. Kuzin, Mikhail P. Petrov +1 more

For the first time an all-optical fiber recirculating loop memory with a long storage time is demonstrated experimentally. Information is stored in the memory by recirculating optical pulses through a closed fiber loop employing all-optical repeaters operating via the stimulated Raman scattering (SRS) effect. The time during which information storage was observed was 10 min. The number of round trips through the loop was more than 100 million.

Experimental vortex transitional nondestructive read-out Josephson memory cell

Shuichi Tahara, Ichiro Ishida, Yumi Ajisawa +1 more

A proposal vortex transitional nondestructive read-out Josephson memory cell is successfully fabricated and tested. The memory cell consists of two superconducting loops in which a single flux quantum is stored and a two-junction interferometer gate as a sense gate. The memory cell employs vortex transitions in the superconducting loops for writing and reading data. The vortex transitional memory operation of the cell contributes to improving its sense discrimination and operating margin. The memory cell is activated by two control signals without timing control signals. Memory cell chips have been fabricated using a niobium planarization process. A±21% address signal current margin and a ±33% sense gate current margin have been obtained experimentally. Successful memory operations of a cell driven by two-junction interferometer gates has been demonstrated. The single flux quantum operations of this memory cell makes it an attractive basic element for a high-speed cache memory.A proposal vortex transitional nondestructive read-out Josephson memory cell is successfully fabricated and tested.
