Two-photon interference using background-free quantum frequency conversion of single photons emitted by an InAs quantum dot
We show that quantum frequency conversion (QFC) can overcome the spectral
distinguishability common to inhomogeneously broadened solid-state quantum emitters.
QFC is implemented by combining single photons from an InAs/GaAs quantum dot (QD) at
980 nm with a 1550 nm pump laser in a periodically poled lithium niobate (PPLN)
waveguide to generate photons at 600 nm with a signal-to-background ratio exceeding
100∶ 1. Photon correlation and two-photon interference measurements confirm that both …
