论文摘要
Siegert关系连接光的一阶相干性能。尽管仅在热度状态下并且在没有相关性的情况下严格有效，但在研究高$β$纳米剂的研究中，这种关系通常扩展到部分连贯的状态，并有助于鉴定激光阈值。我们在不同的设备制度中重新评估了通用的Siegert关系的使用。完整的两次量子 - 光学理论被得出作为获得一阶和二阶相关函数的参考，$ g^{（1）}（τ）$和$ g^{（2）}（τ）$处于稳态状态。我们发现，即使在部分连贯的制度中，只要发射器相关性可以忽略不计，广义的siegert关系也非常适合于$ g^{（2）}（τ）$的近似值，但是在少数emitter纳米仪的量子量子机制中不适当地适用于少量的纳米纳米特人，也不适用于具有亚纳米式纳米式纳米级的量子，或者对具有次级和超级超级式和超级排放的量子。
The Siegert relation connects the first- and second-order coherence properties of light. While strictly valid only in the thermal regime and in the absence of correlations, this relation is routinely extended to the partially coherent regime in the study of high-$β$ nanolasers, where it aids in the identification of the lasing threshold. We re-evaluate the use of a generalized Siegert relation in different device regimes. A full two-time quantum-optical theory is derived as a reference for obtaining first- and second-order correlation functions $g^{(1)}(τ)$ and $g^{(2)}(τ)$ in the steady state. We find that even in the partially coherent regime the generalized Siegert relation is well suited as an approximation to $g^{(2)}(τ)$ as long as emitter correlation are negligible, but does not apply well in the quantum regime of few-emitter nanolasers, or to devices featuring sub- and superradiant emission.
