Experimental and theoretical studies on enhancing nonlinear optical processes at very low light (single-photon) levels in multi-level atomic systems with and without an optical cavity form the focus of this activity. The main objectives of the project include (i) understanding the nonlinear interactions between electromagnetic fields and multi-level atomic systems at low light level, especially the quantum correlation and quantum statistical properties in such systems; (ii) linking the fundamental researches of atomic coherence and quantum interference in multi-level systems to practical device applications in optical communication; and (iii) demonstrating a practical opto-electronic device concept in semiconductor nanostructures based on quantum interference effects in multi-state systems.

这项活动的重点是在有和没有光学腔的多能级原子系统中加强极低光（单光子）能级上的非线性光学过程的实验和理论研究。 该项目的主要目标包括：（i）理解弱光下电磁场与多能级原子系统之间的非线性相互作用，特别是这类系统中的量子关联和量子统计特性;（ii）将多能级系统中原子相干和量子干涉的基础研究与光通信中的实际器件应用相结合;以及（iii）展示基于多状态系统中的量子干涉效应的半导体纳米结构中的实用光电器件概念。
