SYNTHETIC DIAMOND MATERIALS FOR QUANTUM OPTICAL APPLICATIONS AND METHODS OF MAKING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a synthetic diamond material, and a method of synthesizing such material that comprises solid state spin defect photon emitters with an intrinsic inhomogeneous zero phonon line width approaching that of the transform limited value and which is stable with minimal spectral diffusion.;SOLUTION: A synthetic diamond material comprises one or more spin defects having a full width half maximum intrinsic inhomogeneous zero phonon line width of 100 MHz or less, in which the full width half maximum intrinsic inhomogeneous zero phonon line width is averaged over one or both of at least 10 seconds and at least 10 spectral scans. The synthetic diamond material is a CVD synthetic diamond material, and the one or more spin defects are NV-spin defects. A method of fabricating a synthetic diamond material comprises the steps of: selecting a synthetic diamond material comprising a single substitutional nitrogen concentration of 100 ppb or less; and annealing the synthetic diamond material using a multi-stage annealing process.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2017,JPO&INPIT
