- Abstract: Optical microcavities have widely been employed to enhance either the optical
excitation or the photon emission processes for boosting light matter
interactions at nanoscale. When both the excitation and emission processes are
simultaneously facilitated by the optical resonances provided by the
microcavities, as referred to the dual-resonance condition in this article, the
performances of many nanophotonic devices approach to the optima. In this work,
we present versatile accessing of dual-resonance conditions in
deterministically coupled quantum-dot(QD)-micopillars, which enables emission
from exciton (X) - charged exciton (CX) transition with improved single-photon
purity. In addition, the rarely observed up-converted single-photon emission
process is achieved under dual-resonance condition. We further exploit the
vectorial nature of the high-order cavity modes to significantly improve the
excitation efficiency under the dual-resonance condition. The dual-resonance
enhanced light-matter interactions in the quantum regime provides a viable path
for developing integrated quantum photonic devices based on cavity quantum
electrodynamics (QED) effect e.g., highly-efficient quantum light sources and
quantum logical gates.
