Abstract

Local droplet etching (LDE) has been established as a powerful method to produce solid state semiconductor single photon and entangled photons pairs inherently compatible with established semiconductor technology. In this proposal we aim to develop a single photon source emitting at telecom C-band, extending the LDE fabrication approach from the (In)GaAs/AlGaAs system to the III-Sb material system. This would enable the integration of quantum communication already demonstrated for the visible range to be used in the existing optical fiber network, paving the way for the easy use of quantum technologies on a daily basis.
