- Abstract summary: Spectral control in solid state platforms such as color centers, rare earth ions, and quantum dots is attractive for realizing such applications on-chip.
We propose the use of frequency-modulated optical transitions for spectral engineering of single photon emission.
Our results suggest that frequency modulation is a powerful technique for the generation of new light states with unprecedented control over the spectral and temporal properties of single photons.

- Abstract: The ability to shape photon emission facilitates strong photon-mediated
interactions between disparate physical systems, thereby enabling applications
in quantum information processing, simulation and communication. Spectral
control in solid state platforms such as color centers, rare earth ions, and
quantum dots is particularly attractive for realizing such applications
on-chip. Here we propose the use of frequency-modulated optical transitions for
spectral engineering of single photon emission. Using a scattering-matrix
formalism, we find that a two-level system, when modulated faster than its
optical lifetime, can be treated as a single-photon source with a widely
reconfigurable photon spectrum that is amenable to standard numerical
optimization techniques. To enable the experimental demonstration of this
spectral control scheme, we investigate the Stark tuning properties of the
silicon vacancy in silicon carbide, a color center with promise for optical
quantum information processing technologies. We find that the silicon vacancy
possesses excellent spectral stability and tuning characteristics, allowing us
to probe its fast modulation regime, observe the theoretically-predicted
two-photon correlations, and demonstrate spectral engineering. Our results
suggest that frequency modulation is a powerful technique for the generation of
new light states with unprecedented control over the spectral and temporal
properties of single photons.
