我们研究在与一个由经典光场驱动的三能级Λ型发射体耦合的（准）一维光子波导中的关联双光子传输。对于受驱三能级发射体（3LE），波导中的双光子关联比二能级发射体要强得多。受驱的3LE波导呈现电磁诱导透明（EIT），并且我们研究了一个光子和两个光子的EIT标度。我们表明，当入射光子的能量满足EIT的“双光子共振”准则时，两个透射光子在任何距离间隔下都聚集在一起。
We study correlated two-photon transport in a (quasi-)one-dimensional photonic waveguide coupled to a three-level Lambda-type emitter driven by a classical light field. Two-photon correlation is much stronger in the waveguide for a driven three-level emitter (3LE) than a two-level emitter. The driven 3LE waveguide shows electromagnetically induced transparency (EIT), and we investigate the scaling of EIT for one and two photons. We show that the two transmitted photons are bunched together at any distance separation when energy of the incident photons meets "two-photon resonance" criterion for EIT.
