Fluorescent emission of NV centers in diamond pillars embedded in optical fibers: optimization using a hybrid model
Diamond-embedded optical fibers with negatively charged nitrogen-vacancy (NV) centers have great potential for remote and distributed magnetic field sensing. However, the magnetic field sensitivity of the currently proposed fiber configuration is limited. This work uses a numerical approach to investigate the effect of structured diamonds on enhancing the excitation and collection efficiency in an optical fiber through a hybrid modelling approach. The results revealed that a 690-times enhancement is achievable with a pillar-shaped diamond embedded in a fiber.
