Periodic arrays of plasmonic nanoantennas can enhance the directionality of light emission of nearby fluorophores and, therefore, have a great potential for a broad range of applications. Unfortunately, their narrow spectral bandwidth and the anisotropy of their optical resonances limit the use of these structures in applications such as solid state lighting. In this article, we study an alternative...
Nitrogen-vacancy (NV) centers in nanodiamond are photostable single photon emitters at room temperature and are considered to be promising candidates for integrated nanophotonics and quantum information processing. A successful implementation of NV centers in nanophotonic devices requires knowledge about the photophysical properties of each emitter such as brightness, decay rate and quantum efficiency...
Current research in optics, microscopy and quantum information processing frequently deals with the interaction of single quanta of light with single emitters, such as single molecules, quantum dots, or luminescent defect centers in solid materials such as silicon and diamond. Since it is impossible to focus a light wave to below the diffraction limit, i.e., to a size close to the cross section of...
We have derived an efficient model that allows calculating the dynamical single-photon absorption of an emitter coupled to a waveguide. We suggest a novel and simple structure that leads to strong single-photon absorption.
We review recent developments in three-dimensional photonic crystals. State of the art fabrication methods, such as layer-by-layer micromachining, self-assembly and various etching, lithographic and holographic techniques are discussed. We present an overview of optical studies of photonic band gap formation, such as reflectivity, transmission and time-resolved pulse propagation experiments. The fundamental...
