Abstract
We experimentally demonstrated two-photon emission in GaAs/AlGaAs superconducting light emitting diodes (SLEDs), observing EL spectra and g(2) photon correlations corresponding to Cooper-pair recombination. We utilized a superlattice structure and transparent superconducting contacts to enhance pair emission.
