Abstract
Section titled āAbstractāSolid-state systems have potential advantages as platforms for manipulating spin states in several applications, such as quantum computing. Here, it is most desirable to utilize the zero phonon line (ZPL), since its corresponding states are partially shielded from loss and dephasing, but it often directly overlaps in frequency with broadened phonon sidebands at room temperature. The ZPL in solid-state spin systems, such as xenon vacancy centers in diamond and transition metal ions in crystals, is often magnetic dipole (MD), whereas the broadened phonon sideband is predominantly electric dipole (ED). In this letter, we numerically demonstrate a nanorod system that efficiently suppresses ED absorption, and furthermore allows selective detection of emitted radiation originating from MD transitions. The factor of suppression of electric absorption is 1.3Ć104, while the factor of detected ED emission suppression is 20 in the plane. We also show that a nanoparticle suppresses ED emission by a factor of 12. This approach can allow nanoscale decoupling of ZPL from the phonon sidebands, thus facilitating the use of solid-state material systems with MD ZPL transitions for on-chip quantum applications.
