我们报告了一种紧凑的、可扩展的量子光子集成电路，该电路通过将多个可调谐的InGaAs/GaAs量子点单光子源与氮化硅波导电路相结合而实现。电路中的每个波导都由一个独立的、电控的含量子点二极管寻址。我们证明了相邻二极管的量子点发射可以使用斯塔克效应独立地调谐到简并，并且由此产生的光子流是不可区分的。这使得许多光子量子信息处理方案所需的片上hong - ou - mandeltype干涉成为可能。(C) 2018作者。
We report a compact, scalable, quantum photonic integrated circuit realised by combining multiple, tuneable InGaAs/GaAs quantum dot single photon sources with a silicon oxynitride waveguide circuit. Each waveguide in the circuit is addressed by a separate, electrically controlled quantum dot-containing diode. We show that the quantum dot emission from neighbouring diodes can be independently tuned to degeneracy using the Stark Effect and that the resulting photon streams are indistinguishable. This enables on-chip Hong-Ou-Mandel-type interference, as required for many photonic quantum information processing schemes. (C) 2018 Author(s).
