This progress report summarizes the recent advances in the field of diamond nanophotonics. It describes various single photon emitters and the fabrication of optical resonators, and it highlights the recent applications and quantum optics experiments carried out with diamond. The table of contents figure shows a nanodiamond array, superimposed with a finite-difference time-domain simulation of an electric field within a microdisk.

Electrically tunable mid-infrared metasurfaces with nanosecond response times and broad tuning range are reported. Electrical tuning of metasurface reflectivity is achieved by employing strong polaritonic coupling of electromagnetic modes in metallic nanoresonators with voltage-tunable inter-subband transitions in a semiconductor heterostructure designed for a giant electro-optic effect. Experimentally, 300 nm absorption peak tuning and over 30% of reflected signal intensity modulation are demonstrated at around 7 μm wavelength.
- Photochromic Switching of Fano Resonances in Metallic Photonic Crystal Slabs
Felix Bleckmann, Eduard Maibach, Sandra Cordes, Thorsten E. Umbach, Klaus Meerholz and Stefan Linden

Metallic photonic crystal slabs composed of periodic gold nanowire arrays embedded in a photochromic waveguide are studied by optical transmittance spectroscopy. The interaction of the localized plasmon mode of the nanowires and the delocalized waveguide mode gives rise to pronounced Fano resonances. By switching the photochromic waveguide from the transparent to the absorbing state, the Fano dip is strongly suppressed.
- Symmetry-Broken Metamaterial Absorbers as Reflectionless Directional Couplers for Surface Plasmon Polaritons in the Visible Range
Fan Ye, Michael J. Burns and Michael J. Naughton
Article first published online: 29 JUL 2014 | DOI: 10.1002/adom.201400080
Symmetry-broken metal–insulator–metal metamaterial absorbers are shown to have the ability to reflectionlessly couple vertically incident photons into horizontally propagating surface plasmon polaritons in a preferred direction in the visible range. The leverage of the symmetry properties of metamaterials paves ways for a wide range of applications in integrated nanoplasmonics, plasmonic logic, and plasmonic light harvesting.
- Heavy Metal Sensing Using Self-Assembled Nanoparticles at a Liquid–Liquid Interface

A surface-enhanced Raman spectroscopy-based mercury sensor is created by combining a self-assembled nanoparticle film at the liquid–liquid interface with SERS. This powerful, selective, fast, and cheap mercury sensor relies on the interaction of four novel reporters in the organic phase with aqueous ions. With minimal modifications, this platform is capable of the first SERS-based mercury vapor detection.
