High visibility Hong-Ou-Mandel interference from weak-coherent pulses generated by III–V on silicon waveguide integrated lasers

: Gain-switched III–V on silicon waveguide integrated lasers are used to generate weak-coherent pulses compatible with high rate Quantum Key Distribution (QKD) and, by exhibiting Hong-Ou-Mandel interference with 46 ± 2% visibility, suitable for Measurement-Device-Independent-QKD. © 2018 The Author(s)
