This project is aimed at development of several revolutionary new device concepts within the new interdisciplinary research area of Polaritonics, which studies interaction of light with electronic excitations in crystals. PI of this project leads an international collaborative effort in Polaritonics since 2000 coordinating three subsequent European network projects which involve over 15 universities. This collaboration has already yielded a number of spectacular discoveries including the Bose-Einstein condensation of mixed light-matter quasiparticles, features of superfluidity in crystals, spin multistability, ultralow threshold polariton lasing. Development of Polaritonics is led by theory, which predicts new effects, designes new structures and proposes new experiments. This project proposes a program of theoretical research tightly linked with an international experimental effort and aimed at bridging the gap between fundamental discoveries and device applications in Polaritonics. We shall develop and realise and experimentally test several device concepts including the Aharonov-Bohm polariton interferometer and the vertical cavity coherent terahertz light source based on a polariton laser. Fabrication of these devices would manifest a technology breakthrough in opto-electronics with quantum coherent effects brought into everyday life. The new quantum light sources and logic gates are important for realisation of optical computers and enhancement of capacities of optical communication lines. Compact sources of coherent terahertz radiation have their applications in medicine (skin cancer cure), environment protection, industrial sensing, security. The Southampton university will coordinate a multinational research effort in Polaritonics, host leading experts in Polaritonics for short visits, organise a series of international workshops and closely collaborate with several industrial companies including Hitachi, Sharp, Toshiba.

该项目的目的是在新的跨学科研究领域Polaritonics中开发几种革命性的新设备概念，该领域研究光与晶体中电子激发的相互作用。自2000年以来，该项目的PI领导了Polaritonics的国际合作努力，协调了随后的三个欧洲网络项目，涉及超过15所大学。这项合作已经产生了许多惊人的发现，包括混合轻物质准粒子的玻色-爱因斯坦凝聚，晶体中超流性的特征，自旋多稳定性，超低阈值极化激元激光。极化激振学的发展是由理论引导的，它预测新的效应，设计新的结构，提出新的实验。该项目提出了一个与国际实验工作紧密联系的理论研究计划，旨在弥合极化子基础发现和器件应用之间的差距。我们将开发，实现和实验测试几个设备的概念，包括阿哈罗诺夫-玻姆极化激元干涉仪和垂直腔相干太赫兹光源的基础上的极化激元激光器。这些器件的制造将标志着光电子技术的突破，量子相干效应将进入日常生活。新的量子光源和逻辑门对于实现光计算机和提高光通信线路的容量具有重要意义。紧凑型相干太赫兹辐射源在医学（皮肤癌治疗）、环境保护、工业传感、安全等方面有着广泛的应用。南安普顿大学将协调Polaritonics的跨国研究工作，接待Polaritonics的顶尖专家进行短期访问，组织一系列国际研讨会，并与日立，夏普，东芝等多家工业公司密切合作。
