Phys. Rev. Applied 7, 044002 (2017) In the last decade, there has been remarkable progress on the practical
integration of on-chip quantum photonic devices yet quantum state generators
remain an outstanding challenge. Simultaneously, the quantum-dot
photonic-crystal-resonator platform has demonstrated a versatility for creating
nonclassical light with tunable quantum statistics, thanks to a newly
discovered self-homodyning interferometric effect that preferentially selects
the quantum light over the classical light when using an optimally tuned Fano
resonance. In this work, we propose a general structure for the cavity quantum
electrodynamical generation of quantum states from a waveguide-integrated
version of the quantum-dot photonic-crystal-resonator platform, which is
specifically tailored for preferential quantum state transmission. We support
our results with rigorous Finite-Difference Time-Domain and quantum optical
simulations, and show how our proposed device can serve as a robust generator
of highly pure single- and even multi-photon states.
