TL;DR
This paper studies how pure dephasing affects the emission spectra of single photon sources, revealing that dephasing shifts emission peak intensities and explains experimental observations of non-zero peaks at the cavity frequency.
Contribution
It provides a theoretical analysis of dephasing effects on emission spectra, linking it to experimental phenomena in quantum dot microcavities.
Findings
Dephasing shifts emission peak intensities at non-zero detuning.
Explains non-vanishing emission peaks at cavity frequency.
Offers insights into light-matter interaction in lossy microcavities.
Abstract
We investigate the light-matter interaction of a quantum dot with the electromagnetic field in a lossy microcavity and calculate emission spectra for non-zero detuning and dephasing. It is found that dephasing shifts the intensity of the emission peaks for non-zero detuning. We investigate the characteristics of this intensity shifting effect and offer it as an explanation for the non-vanishing emission peaks at the cavity frequency found in recent experimental work.
