我们讨论了耗散对耦合腔阵列系统中单光子输运行为的影响，其中两个最近的腔非局部耦合到一个二能级原子。利用准玻色子图精确求解了单光子的透射振幅。我们分别研究了两种不同的局部和非局部耦合情况。将耗散情况与非耗散情况进行比较，发现系统的耗散增加了单光子传输振幅的中倾角，降低了单光子传输振幅的峰值，使传输谱线宽变宽。需要注意的是，腔耗散对单光子输运谱的影响是不对称的。将非局域耦合与局域耦合进行比较，可以发现，无论是非局域耦合还是局域耦合，单光子透射振幅中倾的增强主要是由原子耗散引起的，而减小峰主要是由腔耗散引起的。而在非局域耦合情况下，耦合强度越强，腔耗散对单光子输运谱的影响越大，原子耗散的影响越弱，可以忽略不计。
We discuss the effects of dissipation on the behavior of single photon transport in a system of coupled cavity arrays, with the two nearest cavities nonlocally coupled to a two-level atom. The single photon transmission amplitude is solved exactly by employing the quasi-boson picture. We investigate two different situations of local and nonlocal couplings, respectively. Comparing the dissipative case with the nondissipative one reveals that the dissipation of the system increases the middle dip and lowers the peak of the single photon transmission amplitudes, broadening the line width of the transport spectrum. It should be noted that the influence of the cavity dissipation to the single photon transport spectrum is asymmetric. By comparing the nonlocal coupling with the local one, one can find that the enhancement of the middle dip of single photon transmission amplitudes is mostly caused by the atom dissipation and that the reduced peak is mainly caused by the cavity dissipation, no matter whether it is a nonlocal or local coupling case. Whereas in the nonlocal coupling case, when the coupling strength gets stronger, the cavity dissipation has a greater effect on the single photon transport spectrum and the atom dissipation affection becomes weak, so it can be ignored.
