SGER: Optical Data Storage and Processing by Photon Echo

首席研究员正在开发一种基于光子回波的高密度、高速光学存储器和光学计算的新概念的研究计划，该计划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。光子延时激光脉冲通过共振原子系统。该系统的反应是在一段延迟时间后发出一束类似激光的光。这就是回声。通过研究光子回波信号的弛豫、调制、偏振等，可以获得关于原子系统内动态相互作用的更详细的信息。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的事实，意味着该系统以某种方式记忆。这是光子回波的基本光学记忆概念。

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.
