Abstract

An on-chip, silicon-compatible light source has long been pursued for telecommunications, with limited success. However, for integrated systems utilizing superconducting detectors, cryogenic operation is already required. This allows these systems to consider sources that room-temperature applications cannot. In such a context, emissive centers embedded in silicon may prove to be a useful light source. Here we demonstrate a waveguide-coupled light-emitting diode in Si, fabricated in an integrated platform with WSi superconducting nanowire detectors. We further demonstrate an LED coupled to eleven detectors in a single integrated photonic device.
