- 論文の詳細を見る
A novel optical buffer memory with shift register function is proposed. The buffer consists of a two-dimensional array of polarization-bistable vertical-cavity surface-emitting lasers (VCSELs), in which the bit state of the optical signal, “0” or “1” is stored as a lasing linear polarization state of 0 or 90°. One-bit optical buffering which is an essential part of the memory, is experimentally demonstrated for the first time using a 980 nm polarization-bistable VCSEL having a mesa structure.
