Abstract
Single-photon emission from excitons in InAs Quantum Dots (QD) embedded in GaAs Tapered Photonic Wires (TPW) already
demonstrated a 0.72 collection efficiency, with TPWs were the apex is the sharp end of the cone. Going to alternate designs, still
based on the idea of the adiabatic deconfinement of the quasi-Gaussian emission mode, but with inverted TPW where the apex is
the cone's base, leads to even larger efficiencies. In addition, these inverted TPWs make the electric pumping of the emitters
compatible with these large efficiencies.
