- Large-Area Antenna-Assisted SEIRA Substrates by Laser Interference Lithography
Shahin Bagheri, Harald Giessen and Frank Neubrech
Article first published online: 31 JUL 2014 | DOI: 10.1002/adom.201400218
Laser interference lithography is utilized to fabricate large-area plasmonic antenna substrates with tunable plasmonic resonances in the near- and mid-infrared spectral range for surface-enhanced infrared absorption (SEIRA). The broad applicability of such SEIRA substrates is demonstrated by enhancing the infrared vibrational signals of a monolayer octadecanethiol and by monitoring the ultraviolet degradation of a polymer via the decrease of its specific vibrational modes.

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.
- Ultrafast Electrically Tunable Polaritonic Metasurfaces
Jongwon Lee, Seungyong Jung, Pai-Yen Chen, Feng Lu, Frederic Demmerle, Gerhard Boehm, Markus-Christian Amann, Andrea Alù and Mikhail A. Belkin
Article first published online: 30 JUL 2014 | DOI: 10.1002/adom.201400185
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
Article first published online: 30 JUL 2014 | DOI: 10.1002/adom.201400187
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.
