“…We observe a deep transparency minimum in the calculated spectra, caused by Fano interference between the plasmon resonance and the quantum emitter transition. A similar phenomenon was found in the previous literature [10], where the quantum emitter (quantum dot) was modeled using a dielectric function as a single Lorentz term [10,[67][68][69]. This latter model is valid only in the low excitation limit, where quantum-mechanical coherences between the ground and excited states of a quantum emitter can be neglected, a condition that is satisfied at the intensity considered in [10] and in the present study.…”

We propose two complementary approaches for solution of the coupled Maxwell-Liouville equations within the finite-difference time domain (FDTD) framework. The two methods are specifically designed to eliminate self-interaction, which often appears spuriously in simulation of the coupled Maxwell-Liouville equations, and hence can be used for modeling of single as well as ensembles of quantum emitters (such as molecules or quantum dots) in an arbitrary dielectric environment. One approach borrows from the familiar total field-scattered field technique that has been applied in the past in a different context. The second recognizes an opportunity to average over the electric field at a set of specifically chosen points around the quantum emitter. The methods introduced are applied to two problems of growing current interest that also present useful test cases. One is the modeling of spontaneous emission, where comparison with an analytical solution illustrates the accuracy and efficiency of the methodology. The second is quantum-emitter-induced transparency in a resonator formed by two gold ellipsoids, where Fano interferences suggest interesting potential applications.

“…The Q is obtained by analyzing the signal decay with the time. Further information related to FDTD simulations can be found in Ref [40]. We have modeled the re-grown hole as a vertical circular cylinder with radius r b on the bottom part that corresponds to the pre-pattern.…”

Abstract:We investigate L7 photonic crystal microcavities (PCMs) fabricated by epitaxial re-growth of GaAs pre-patterned substrates, containing InAs quantum dots. The resulting PCMs show hexagonal shaped nano-holes due to the development of preferential crystallographic facets during the re-growth step. Through a careful control of the fabrication processes, we demonstrate that the photonic modes are preserved throughout the process. The quality factor (Q) of the photonic modes in the re-grown PCMs strongly depends on the relative orientation between photonic lattice and crystallographic directions. The optical modes of the re-grown PCMs preserve the linear polarization and, for the most favorable orientation, a 36% of the Q measured in PCMs fabricated by the conventional procedure is observed, exhibiting values up to ~6000. The results aim to the future integration of site-controlled QDs with high-Q PCMs for quantum photonics and quantum integrated circuits.
