A planar dielectric antenna for directional single-photon emission and near-unity collection efficiency
A planar dielectric antenna for directional single-photon emission and near-unity collection efficiency
Single photon sources have been discussed as the building blocks of quantum cryptography, optical quantum computation, spectroscopy, and metrology. However, when using sources based on single emitters, the success of these proposals depends on the ability to achieve near-unity collection efficiency into well-defined modes. Some of the current state-of-the-art efforts …
