中文摘要: 面向量子通信和量子计算应用,室温的电注入单光子源的实现将具有重要的科学意义和实用价值。到目前为止还未看到室温下电注入单光子源的报道。我们将在电注入量子阱发光材料上制作光子晶体孔,控制孔的深度达到量子阱层,在光子晶体孔内引入胶体量子点,控制量子点浓度,制作电极,利用光子晶体增强量子阱发光与量子点的相互作用,利用共振能量转移原理(FRET)实现量子阱发光到量子点的高效率能量转移,实现量子点高效率电注入发光;通过减少量子点浓度,研究新型高效率、室温电注入单光子发射特性。本项目将采用量子阱与量子点的相互作用原理和微加工技术,设计、制作并表征电注入单光子源,并实现室温工作。该研究无论在工作原理上,实现技术以及原型器件上都是创新的。该项目的实施和完成,将在量子通信和量子信息处理中光源方面取得学术创新和高技术突破,达到国际领先水平,将推动我国量子通信和量子信息处理事业的快速发展。

英文摘要: According to quantum communication and quantum computing applications, room temperature, electrical injected single photon sources display important scientific significance and practical value. Up to the present, room temperature, electrical injected single photon sources have not been reported. We will etch photonic crystal holes into the electrical injected quantum well light-emitting materials, control the depth of the hole to reach the quantum well layer and introduce colloidal quantum dots in the photonic crystal holes. By controlling the concentration of quantum dots and making the electrode, the energy will transfer efficiency from quantum well light-emitting materials to quantum dots under the principle of Forster resonant energy transfer (FRET). Furthermore, we will research on emitting characteristics with high efficiency, room temperature electric injected single photon sources by reducing the concentration of quantum dots. Focusing on the interaction principle between quantum wells and quantum dots, using micro-processing technology, we will design, fabricate and detect electrical injected single photon sources, which will work at room temperature. This study is very innovative in working principle, fabrication technology and prototype devices. The implementation and completion of this project will m
