We demonstrate cavity-enhanced Raman emission from a single atomic defect in a solid. Our platform is a single silicon-vacancy center in diamond coupled with a monolithic diamond photonic crystal cavity. The cavity enables an unprecedented frequency tuning range of the Raman emission (100 GHz) that significantly exceeds the spectral inhomogeneity of silicon-vacancy centers in diamond nanostructures. We also show that the cavity selectively suppresses the phonon-induced spontaneous emission that degrades the efficiency of Raman photon generation. Our results pave the way towards photon-mediated many-body interactions between solid-state quantum emitters in a nanophotonic platform.
我们展示了来自固体中单原子缺陷的腔增强拉曼发射。我们的平台是与单片金刚石光子晶体腔耦合的单个硅空位中心。该腔使拉曼发射的频率调谐范围前所未有（100GHz），大大超过了金刚石纳米结构中硅空位中心的光谱不均匀性。我们还表明，该腔选择性地抑制了声子诱导的自发发射，从而降低了拉曼光子产生的效率。我们的结果为在纳米光子平台中固态量子发射器之间的光子介导多体相互作用铺平了道路。
