SGER: Optical Data Storage and Processing by Photon Echo

首席研究员正在开发一个基于光子回波的高密度、高速光存储和光计算的新概念的研究项目，该概念具有对时间和空间编码数据进行大规模并行实时处理的内在潜力。光子时间延迟激光脉冲通过共振原子系统。在一定的延迟时间后，系统通过发射一束类似激光的光来响应。这是回声。通过对光子回波信号的弛豫、调制、极化等特性的研究，可以得到原子系统内部动态相互作用的详细信息。另一方面，原子系统在激光脉冲通过后发出一段时间的光脉冲，这一事实意味着该系统以某种方式记忆。这是光子回波的基本光存储概念。

The Principal Investigator is developing a research program in a novel concept of high-density, high- speed optical memory and optical computing based on photon echoes, that has inherent potential for massively parallel real-time processing of temporally as well as spatially encoded data. Photon time- delayed laser pulses pass through a resonant atomic system. The system responds by emitting, after a certain delay time, a burst of laser-like light. This is the echo. By studying the relaxation, modulation, polarization, etc., of the photon echo signal, much detailed information about the dynamic interactions within the atomic system can be obtained. On the other hand, the fact that the atomic system emits a light pulse of some time after the passage of laser pulses, implies that the system somehow remembers. This is the basic optical memory concept of photon echoes.
