我们指出，单个有机染料分子沉积在靠近光子芯片上的光波导处，可以作为单光子源。一个薄薄的氮化硅条形波导有望从一个单一的二苯基叔丁烯分子中收集28%的光子。这些分子还可以提供大的局域光学非线性，这足以通过每个光子2度的微分相移来区分一个光子或两个光子。这种新的原子-光子界面可能被用作处理量子信息的资源。
We point out that individual organic dye molecules, deposited close to optical waveguides on a photonic chip, can act as single-photon sources. A thin silicon nitride strip waveguide is expected to collect 28% of the photons from a single dibenzoterrylene molecule. These molecules can also provide large, localized optical nonlinearities, which are enough to discriminate between one photon or two through a differential phase shift of 2 degrees per photon. This new atom-photon interface may be used as a resource for processing quantum information.
