Storing optical pulses using resonators is a key enabler of many applications, for example in optical communications, nonlinear optics or sensing. One of the ‘fundamental’ limitations of optical resonators is that they…
The ability to measure very precise alignments and displacements is a key requirement for many steps in semiconductor fabrication and manufacturing, for example, during lithography or wafer bonding. Using small…
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…
Epsilon-near-zero materials promise non-linear optical enhancement, light transport through arbitrary channels, wave-front shaping and control over optical emission. Typically implemented using either naturally…
Similar to microelectronic circuits, future photonic chips will include multiple layers of different materials to integrate functionality in a single circuit. One of the key challenges is to couple light between the…
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…
One of the key tasks in integrated photonics is the separation or demultiplexing of multiple different wavelength channels that are transported through the same waveguide. One way to separate different wavelength is to…
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…
