利用主动光学中心阵列来控制光与物质相互作用的哈密顿量是近年来的研究热点。原子阵列与可见光子的集体相互作用可以引起定向增强的吸收或发射，这使得宽带和强原子-光子界面的工程成为可能。在这里，我们报告的观察远程合作共振的稀土离子阵列可控地注入到一个固态锂离子微环谐振器。我们表明，合作效应可以观察到在一个有序的离子阵列远远超出光的波长。我们观察到增强发射从腔诱导的珀塞尔增强和阵列诱导的集体共振在低温下。工程集体共振作为增强光-物质相互作用的范例可以抑制自由空间自发辐射。承载稀土离子的硼酸锂的多功能性可以为可扩展和多路复用的量子网络打开量子光子器件工程的可能性。
Engineering arrays of active optical centers to control the interaction Hamiltonian between light and matter has been the subject of intense research recently. Collective interaction of atomic arrays with optical photons can give rise to directionally enhanced absorption or emission, which enables engineering of broadband and strong atom-photon interfaces. Here, we report on the observation of long-range cooperative resonances in an array of rare-earth ions controllably implanted into a solid-state lithium niobate micro-ring resonator. We show that cooperative effects can be observed in an ordered ion array extended far beyond the light’s wavelength. We observe enhanced emission from both cavity-induced Purcell enhancement and array-induced collective resonances at cryogenic temperatures. Engineering collective resonances as a paradigm for enhanced light-matter interactions can enable suppression of free-space spontaneous emission. The multi-functionality of lithium niobate hosting rare-earth ions can open possibilities of quantum photonic device engineering for scalable and multiplexed quantum networks.
