中文摘要：

我们研究了与包含三能级原子的纳米腔相耦合的一维耦合谐振器波导中的单光子散射,分别讨论了纳米腔与耦合谐振器波导局域和非局域的两种耦合方式。在局域耦合的情况下,不同偏振光子的透射及反射波谱关于共振点对称。而在非局域情况下,透射和反射系数中的对称性消失,峰和谷的位置向失谐较大处移动。耗散对单光子散射也会产生影响。

英文摘要：

We research the scattering properties of a single photon transporting in a coupled-resonator waveguide（CRW） coupled to a nanocavity with a three-level atom embedded.Two different types of couplings between nanocavity and CRW are discussed,and one type is the local coupling while the other is nonlocal coupling.It is shown that the transmission and reflection spectrum for photons with different polarizations are symmetric for the local coupling.While the symmetry in the transmission and reflection spectrum is destroyed in the nonlocal coupling case.Meanwhile the positions of peaks and troughs of the spectrum are shifted towards the large values of the detuning.The effects of dissipation on the scattering properties of single photon are also proved in this research.
