Abstract:
Recently, the nitrogen vacancy (NV) center has emerged as a
deterministic single-photon source at room temperature.
However, the presence of phonon sideband emission limits
the use of NV centers in various quantum optical applications. Here we report a novel way to suppress the phonon
sideband emission of NV centers aided with the enhancement of zero phonon line intensity using photonic crystals
at room temperature. We study the photonic stop gap
mediated charge state conversion in NV centers. The
enhancement of phonon sideband emission from the same
structures by implementing a different measurement geometry is also discussed. The studies open new avenues in
studying the NV center-based quantum nanophotonics
and biophotonics.
