Abstract
Section titled âAbstractâAbstract Metasurfaces have the ability to control classical and nonâclassical states of light to achieve controlled emission even at the level of a single emitter. Here, the Kerker condition induced emission rate enhancement with strong directivity is unveiled from a single emitter integrated within a dielectric metasurface consisting of silicon nanoâdisks. The simulation and analytical calculations attest the Kerker condition with unidirectional light scattering evolved by the constructive interference between electric dipole, toroidal dipole, and the magnetic quadrupole. The results evince spatiallyâdependent enhanced local density of optical states, which reciprocates localized field intensity. The emission rate enhancement of 400 times is achieved close to the zero phonon line of the nitrogenâvacancy center with superior emission directivity and collection efficiency. The results have implications in onâdemand single photon generation, spinâphoton interface, manyâbody interactions, and strong coupling.
