- Abstract summary: Single-photon sources based on three-level systems are limited due to a lack of high photon indistinguishability.
Here, we tailor the cavity-enhanced spontaneous emission from a ladder-type three-level system in a single epitaxial quantum dot (QD) through stimulated emission.
The stimulated XX-X emission modifies the X decay dynamics and yields improved polarized single-photon source characteristics.

- Abstract: The coherent interaction of electromagnetic fields with solid-state two-level
systems can yield deterministic quantum light sources for photonic quantum
technologies. To date, the performance of semiconductor single-photon sources
based on three-level systems is limited mainly due to a lack of high photon
indistinguishability. Here, we tailor the cavity-enhanced spontaneous emission
from a ladder-type three-level system in a single epitaxial quantum dot (QD)
through stimulated emission. After populating the biexciton (XX) of the QD
through two-photon resonant excitation (TPE), we use another laser pulse to
selectively depopulate the XX state into an exciton (X) state with a predefined
polarization. The stimulated XX-X emission modifies the X decay dynamics and
yields improved polarized single-photon source characteristics such as a source
brightness of 0.030(2), a single-photon purity of 0.998(1), and an
indistinguishability of 0.926(4). Our method can be readily applied to existing
QD single-photon sources and expands the capabilities of three-level systems
for advanced quantum photonic functionalities.
