我们提出并演示了一种新型的频率选择光学存储器，可以在时域和频域中写入和读取数据。时间 16 位数据通过累积光子回波逐位存储存储在 Eu3+:Y2SiO5 7F0-5D0 跃迁非均匀线内的 103 个频率地址处，在直径 240 μm 的单点中产生 1.6 kbit 的总存储容量。该实验成功的关键是该材料的长相移时间和缺乏光谱扩散。
We propose and demonstrate a novel type of frequency-selective optical memory that writes and reads the data in both the time domain and the frequency domain. Temporal 16-bit data were stored by accumulated-photon-echo bit-by-bit storage at 103 frequency addresses within the inhomogeneous line of the 7F0-5D0 transition of Eu3+:Y2SiO5, which yields a total memory capacity of 1.6 kbits in a single spot of 240-mu-m diameter. The keys to the success of this experiment are this material's long dephasing time and lack of spectral diffusion.
