Mollow三重态的光子关联

Photon Correlations from the Mollow Triplet

Juan Camilo López Carreño, Elena del Valle, Fabrice P. Laussy

摘要:

莫洛三重态的光致发光峰之间的光子相关性已经知道了很长一段时间,最近被誉为预示着单光子源的资源。在这里,我们提供了所有阶次的光子相关性的全貌(我们明确地处理多达四个光子),并且对包含峰值的特殊频率窗口没有限制。我们发现,丰富的多光子物理位于峰之间,由于过渡涉及虚光子,从而更强的相关性比那些通过修饰状态的过境。具体来说,我们表明,这种排放发生在束的光子,而不是连续的,虽然相关的,光子。我们提供了对Mollow三重态的发射进行频率滤波的方法,以将其转变为通用且可调谐的光子源,原则上允许光子发射的所有场景,其优点已经在单光子水平上,即,提供比已知的那些更强相关的预示单光子源。

英文摘要:

Photon correlations between the photoluminescence peaks of the Mollow triplet have been known for a long time, and recently hailed as a resource for heralded single-photon sources. Here, we provide the full picture of photon-correlations at all orders (we deal explicitly with up to four photons) and with no restriction to the peculiar frequency windows enclosing the peaks. We show that a rich multi-photon physics lies between the peaks, due to transition involving virtual photons, and thereby much more strongly correlated than those transiting through the dressed states. Specifically, we show that such emissions occur in bundles of photons rather than as successive, albeit correlated, photons. We provide the recipe to frequency-filter the emission of the Mollow triplet to turn it into a versatile and tunable photon source, allowing in principle all scenarios of photon emission, with advantages already at the one-photon level, i.e., providing more strongly correlated heralded single-photon sources than those already known.
