摘要: A composite optical microcavity, in which nitrogen vacancy (NV) centers a diamond nanopillar are coupled to whispering gallery modes silica microsphere, is demonstrated. Nanopillars with diameter as small 200 nm fabricated from bulk crystal by reactive ion etching and positioned nanometer precision near the equator of microsphere. The nanopillar-microsphere system overcomes poor controllability nanocrystal-based microcavity takes full advantage exceptional spin properties NV ultrahigh quality factor microspheres.
