Abstract
We propose a field-based design of the dielectric antennas to efficiently interface diamond color centers with a Gaussian propagating far field. This antenna design provides an efficient spin-photon interface with a Purcell factor over 400 and a 93% mode overlap to a 0.4 numerical aperture Gaussian far-field mode. The antenna design is robust to the fabrication imperfections, such as variations in the geometry of the dielectric perturbations and the emitter dipole location or orientation. The field-based dielectric antenna design provides an efficient free-space interface to closely packed arrays of quantum memories for arrayed quantum sensors, multiplexed quantum repeaters, and modular quantum computers.
