| contents | Photonic Integrated Circuits (PIC)s are a promising contender for quantum information technologies. The spectral purity of photons is one of the key attributes of PIC photon-pair sources. The dual-pulse pump manipulation technique [1] showed >99% purity in ring-resonator photon-pair sources. Here, we have developed a PIC to shape a pulse into dual, triple and quadruple pulses and investigated the effect of these pump pulse configurations on the purity. Our results show that more complex configurations over dual-pulse do not result in comparatively higher purity but allow accurate control over choosing arbitrary values of the purity. |
