    "abstract": "It is a difficult engineering task to create distinct solid state single\nphoton sources which nonetheless emit photons at the same frequency. It is also\nhard to create entangled photon pairs from quantum dots. In the spirit of\nquantum engineering we propose a simple optical circuit which can, in the right\ncircumstances, make frequency distinguishable photons frequency\nindistinguishable. Our circuit can supply a downstream solution to both\nproblems, opening up a large window of allowed frequency mismatches between\nphysical mechanisms. The only components used are spectrum analysers/prisms and\nan Acousto-Optic Modulator. We also note that an Acousto-Optic Modulator can be\nused to obtain Hong-Ou-Mandel two photon interference effects from the\nfrequency distinguishable photons generated by distinct sources.",
