体相和纳米晶SiC中的原子尺度色心是与光纤、量子信息处理和环境条件下的传感兼容的量子光子学的有前途的系统。色心作为SiC中稳定的单光子源,是量子光子学和通信的关键元素。结果表明,SiC中至少存在S = 1和S = 3/2的两族色心,它们在室温及更高温度下仍具有自旋能级光学取向的性质。自旋态的初始化,操纵和读出的光检测磁共振(ODMR),水平反交叉和交叉弛豫。最近,我们在ODMR光谱中观察到了“烧孔”效应,这使得ODMR谱线可以缩小大约一个数量级,这大大增加了自旋中心技术应用的可能性。
Atomic-scale colour centres in bulk and nanocrystalline SiC are promising systems for quantum photonics compatible with fiber optics, quantum information processing and sensing at ambient conditions. Colour centres which acts as stable single photon sources in SiC can be key elements for quantum photonics and communications. It has been shown that there are at least two families of colour centres in SiC with S = 1 and S = 3/2, which have the property of optical alignment of the spin levels even at room temperature and above. The spin state can be initialized, manipulated and readout by means of optically detected magnetic resonance (ODMR), level anticrossing and cross-relaxation. Recently, we observed the effects of “hole burning” in the ODMR spectra, which made it possible to narrow the ODMR line by approximately an order of magnitude, which substantially increases the possibilities of technological applications of spin centres.
