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.

首席研究员正在开发一项基于光子回波的高密度、高速光学存储器和光学计算新概念的研究项目，该项目具有大规模并行实时处理时间和空间编码数据的内在潜力。 光子延时激光脉冲穿过共振原子系统。 该系统通过在一定的延迟时间后发出一阵类似激光的光来做出响应。 这就是回声。 通过研究光子回波信号的弛豫、调制、偏振等，可以获得有关原子系统内动态相互作用的更多详细信息。 另一方面，原子系统在激光脉冲通过一段时间后发射光脉冲，这一事实意味着该系统以某种方式进行记忆。 这是光子回波的基本光学记忆概念。
