- Abstract summary: We report on the integration of near-transform-limited silicon defects into microdisk resonators fabricated in a CMOS-compatible 4H-Silicon Carbide-on-Insulator platform.
We demonstrate a single-emitter cooperativity of up to 0.8 as well as optical superradiance from a pair of color centers coupled to the same cavity mode.

- Abstract: An outstanding challenge for color center-based quantum information
processing technologies is the integration of optically-coherent emitters into
scalable thin-film photonics. Here, we report on the integration of
near-transform-limited silicon vacancy (V$_{\text{Si}}$) defects into microdisk
resonators fabricated in a CMOS-compatible 4H-Silicon Carbide-on-Insulator
platform. We demonstrate a single-emitter cooperativity of up to 0.8 as well as
optical superradiance from a pair of color centers coupled to the same cavity
mode. We investigate the effect of multimode interference on the photon
scattering dynamics from this multi-emitter cavity quantum electrodynamics
system. These results are crucial for the development of quantum networks in
silicon carbide and bridge the classical-quantum photonics gap by uniting
optically-coherent spin defects with wafer-scalable, state-of-the-art
photonics.
