Query: A Fabry-Perot Microcavity for Diamond-Based Photonics   Open Fabry-Perot microcavities represent a promising route for achieving a
quantum electrodynamics (cavity-QED) platform with diamond-based emitters. In
particular, they offer the opportunity to introduce high purity, minimally
fabricated material into a tunable, high quality factor optical resonator.
Here, we demonstrate a fiber-based microcavity incorporating a thick (> 10
{\mu}m) diamond membrane with a finesse of 17,000, corresponding to a quality
factor Q ~ $10^6$. Such minimally fabricated, thick samples can contain
optically stable emitters similar to those found in bulk diamond. We observe
modified microcavity spectra in the presence of the membrane, and develop
analytic and numerical models to describe the effect of the membrane on cavity
modes, including loss and coupling to higher-order transverse modes. We
estimate that a Purcell enhancement of approximately 20 should be possible for
emitters within the diamond in this device, and provide evidence that better
diamond surface treatments and mirror coatings could increase this value to 200
in a realistic system.
