Q-factor enhancement in all-dielectric anisotropic nanoresonators
It is proposed and demonstrated that the Q factor of optical resonators can be significantly enhanced by introducing an extra anisotropic cladding. We study the optical resonances of all-dielectric core-shell nanoresonators and show that radially anisotropic claddings can be employed to squeeze more energy into the core area, leading to stronger light confinement and thus significant Q-factor enhancement. We further demonstrate that the required homogenous claddings of unusual anisotropy...[Show more]
