Abstract

Single-photon sources are crucial components for photonic quantum technologies. Recently, robust solid-state quantum light emitters have been discovered in 2D materials. We demonstrate how single photons originating from 2D materials can be efficiently collected and routed either on a photonic chip or beamed into the far field. For on-chip coupling, we deposit GaSe crystals with embedded single-photon emitters onto silicon nitride rib waveguides. For efficient far-field collection, we 3D-print elliptical polymer microlenses on an array of hBN nanocrystals hosting single-photon emitters.
