- Abstract: In this paper, we demonstrate the infrared photoluminescence emission from
Ge(Si) quantum dots enhanced with collective Mie modes of silicon nanopillars.
We show that the excitation of band edge dipolar modes of a linear nanopillar
array results in strong reshaping of the photoluminescence spectra. Among other
collective modes, the magnetic dipolar mode with the polarization along the
array axis contributes the most to the emission spectrum exhibiting an
experimentally measured Q-factor of around 500 for an array of 11 pillars. The
results belong to the first experimental evidence of light emission enhancement
of quantum emitters applying collective Mie resonances and therefore represent
an important contribution to the new field of active all-dielectric
meta-optics.

Spontaneous emission is a fundamental out-of-equilibrium process in which an excited quantum emitter relaxes to the ground state due to quantum fluctuations.
One way to modify these photon-mediated interactions is to alter the dipole radiation patterns of the emitter, e.g., by placing photonic crystals near them.
Our study delves into the interaction between these directional emission patterns and the aforementioned variables, revealing the untapped potential to fine-tune collective quantum optical phenomena.
