提出了一种具有移位寄存器功能的新型光缓冲存储器。该缓冲器由偏振垂直腔面发射激光器（VCSEL）的二维阵列组成，其中光信号的比特状态“0”或“1”被存储为0或90°的激光线性偏振状态。一位的光缓冲，这是一个重要的部分的存储器，实验证明首次使用980 nm的偏振反射VCSEL具有梅萨结构。
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.
