可调谐带隙结构的单光子发射效率

Efficiency of tunable band-gap structures for single-photon emission

Ho Trung Dung, Ludwig Knöll, Dirk-Gunnar Welsch

摘要:

最近提出的单光子发射源的可调平面带隙结构的基础上的效率进行检查。分析的基础是对总衰减率和"辐射“衰减率、发射辐射能量的期望值及其准直锥的研究。结果表明,在缺陷带隙结构的缺陷共振附近的频率范围内工作的方案比在完美带隙结构的带边附近工作的方案更有效。

英文摘要:

The efficiency of recently proposed single-photon emitting sources based on tunable planar band-gap structures is examined. The analysis is based on the study of the total and ``radiative'' decay rates, the expectation value of emitted radiation energy and its collimating cone. It is shown that the scheme operating in the frequency range near the defect resonance of a defect band-gap structure is more efficient than the one operating near the band edge of a perfect band-gap structure.
