Guest Editorial: Nanophotonics for Communications

The communication industry has been the major driving force behind the extraordinary progress made in photonics that contributed to an age of information explosion over the past two decades. In the recent past, scientific breakthroughs have brought tremendous momentum to this field of research and we have observed an outbreak of interest in nanoscale materials and devices with revolutionary app...

Diamond nanophotonics

We demonstrate the coupling of single color centers in diamond to plasmonic and dielectric photonic structures to realize novel nanophotonic devices. Nanometer spatial control in the creation of single color centers in diamond is achieved by implantation of nitrogen atoms through high-aspect-ratio channels in a mica mask. Enhanced broadband single-photon emission is demonstrated by coupling nit...

Integrated diamond networks for quantum nanophotonics.

We demonstrate an integrated nanophotonic network in diamond, consisting of a ring resonator coupled to an optical waveguide with grating in- and outcouplers. Using a nitrogen-vacancy color center embedded inside the ring resonator as a source of photons, single photon generation and routing at room temperature is observed. Furthermore, we observe a large overall photon extraction efficiency (1...
