Controlled Coupling of Nanoparticles to Photonic Crystal Cavities

摘要

We demonstrate a hybrid approach for the realization of novel nanophotonic devices by combining lithographic fabrication techniques with a nano-manipulation method. In particular, we report on the fabrication of photonic crystal cavities as a platform to which arbitrary emitters or other nanoscopic objects can be coupled in a deterministic way by exploiting the manipulation capabilities of an atomic force microscope. In addition, the optical properties of such particle-cavity systems are analyzed with regard to changes of the quality factor and resonance wavelength of the cavity mode. Our approach is well suited to create improved single photon sources and also complex photonic devices with several emitters coupled coherently via shared cavity modes.
