- Title: A vertically-loaded diamond microdisk resonator spin-photon interface
- Authors: Yuqin Duan, Kevin C. Chen, Dirk R. Englund and Matthew E. Trusheim
- Abstract summary: The VLDMoRt achieves a Purcell enhancement of 172 with $39%$ of the emitted light collected within a $textNA$ of 0.6, leading to a total external spin-photon collection efficiency of 0.33.
As the design is compatible with established nanofabrication techniques and couples to low-NA modes accessible by cryogenic free-space optical systems, it is a promising platform for efficient spin-photon interfaces based on diamond quantum emitters.

- Abstract: We propose and optimize a vertically-loaded diamond microdisk resonator
(VLDMoRt) coupled to a nitrogen-vacancy (NV) center in diamond for efficient
collection of zero-phonon-line emission into low numerical aperture
($\text{NA}$) free-space modes. The VLDMoRt achieves a Purcell enhancement of
172 with $39\%$ of the emitted light collected within a $\text{NA}$ of 0.6,
leading to a total external spin-photon collection efficiency of 0.33. As the
design is compatible with established nanofabrication techniques and couples to
low-NA modes accessible by cryogenic free-space optical systems, it is a
promising platform for efficient spin-photon interfaces based on diamond
quantum emitters.

diamond [0.0]
The nitrogen-vacancy center in diamond is an attractive resource for the generation of remote entangled states.
Here, we couple a nitrogen-vacancy center with a narrow extrinsically broadened linewidth, hosted in a micron-thin membrane, to the mode of an open optical microcavity.
The resulting Purcell factor of $sim$1.8 increases the fraction of zero-phonon line photons to above 44%, leading to coherent photon emission rates exceeding four times the state of the art.

Tin-vacancy center (SnV) in diamond is a promising spin-photon interface with desirable optical and spin properties at 1.7 K.
We introduce a new platform that overcomes these challenges - SnV centers in uniformly strained thin diamond membranes.
The presence of crystal strain suppresses temperature dependent dephasing processes, leading to a considerable improvement of the coherence time up to 223 $mu$s at 4 K.
