One of the exciting application areas for optical metasurfaces is holography. Through a clever arrangement of meta-atoms we use metasurfaces to display almost any computer-generated hologram, allowing the display of…
Epsilon-near-zero (ENZ) materials are materials that have a spectral region where the permittivity is below zero. This leads to unconventional optical behaviour, ranging from light propagation through arbitrary…
As part of the nanofab spin-off from the Photonics online meetup (POM) Dr Schulz gave a short tutorial on how to make a good plasmonic metasurface. The recorded presentation is now available as part of the “Flash Talk”…
Metasurfaces based on epsilon-near-zero materials show very strong nonlinear responses and allow coupling of light to optical modes in the epsilon-near-zero thin film that are otherwise not accessible at normal…
Dicke superradiance is a phenomenon where multiple closely spaced emitters can enter a collective excited state with a much shorter lifetime than the excited states of the individual emitters. Together with…
Our recent APL Photonics paper on flexible epsilon-near-zero metamaterials has been highlighted in the News & Views section of the July Issue of Nature Photonics. Congratulations to everyone involved.
In this work, we present a flexible metasurface that operates in the mm-wavelength region. A major problem in modern technology is that many systems, e.g. antennas, are designed for specific functionality. If new…
Last week Sebastian Schulz attended the inaugeral IEEE British and Irish Conference on Optics and Photonics (BICOP) held at the Royal Society in London. He presented a poster on our work on overcoming the…
Good news everyone: Dr Schulz has been awarded a Royal Society research grant for his proposal “Tuneable, dielectric metasurfaces on epsilon-near-zero films”. Stay tuned for progress updates. And if you are interested…
