Abstract

Integrated diamond photonics presents one of the most promising platforms for solid-state quantum computing due to diamond’s high refractive index, large electronic bandgap and its large number of defects with highly stable fluorescence of single photons and coherent electron spin control like the silicon vacancy. This work presents the design, simulation, fabrication and measurement of free-standing diamond photonic crystal cavities from bulk single-crystal diamond substrate for emission enhancement of the SiV^-. Simulation yields Q-factors of up to 2.4 million and normalised mode volumes down to 0.52. Confocal measurements of the fabricated devices yield Q-factors of up to 1800 near the SiV- zero phonon line. These diamond resonators offer a promising approach to realizing large-scale diamond quantum registers.
