Abstract
Section titled āAbstractāOpen Fabry-Perot microcavities represent a promising route for achieving a\nquantum electrodynamics (cavity-QED) platform with diamond-based emitters. In\nparticular, they offer the opportunity to introduce high purity, minimally\nfabricated material into a tunable, high quality factor optical resonator.\nHere, we demonstrate a fiber-based microcavity incorporating a thick (> 10\n{\mu}m) diamond membrane with a finesse of 17,000, corresponding to a quality\nfactor Q ~ $10^6$. Such minimally fabricated, thick samples can contain\noptically stable emitters similar to those found in bulk diamond. We observe\nmodified microcavity spectra in the presence of the membrane, and develop\nanalytic and numerical models to describe the effect of the membrane on cavity\nmodes, including loss and coupling to higher-order transverse modes. We\nestimate that a Purcell enhancement of approximately 20 should be possible for\nemitters within the diamond in this device, and provide evidence that better\ndiamond surface treatments and mirror coatings could increase this value to 200\nin a realistic system.\n
