本文研究了具有非线性色散关系的一维波导中的可控单光子输运。引入一个额外的腔场来驱动发射极的一个能级跃迁。在共振情况下，当额外腔中不包含光子时，输入单光子将被反射;当腔中包含一个光子时，可以获得输入单光子的完全透射。在非共振情况下，单光子输运也可以由腔的参数控制。因此，我们表明，单光子输运可以控制一个额外的腔场。
We study controllable single-photon transport in a one-dimensional waveguide with a nonlinear dispersion relation coupled to a three-level emitter in a cascade configuration. An extra cavity field is introduced to drive one of the level transitions of the emitter. In the resonance case, when the extra cavity does not contain photons, the input single photon will be reflected; when the cavity contains one photon, the full transmission of the input single photon can be obtained. In the off-resonance case, the single-photon transport can also be controlled by the parameters of the cavity. Therefore, we show that single-photon transport can be controlled by an extra cavity field.
