We have a wide-ranging portfolio of research, all focused un using nanophotonics to control light and its propagation.
The time-bandwidth relation that states that the longer a resonator stores energy, the narrower the bandwidth of supported frequencies and it is an intrinsic limitation to conventional resonators. However, this…
Photonic crystal devices have big potential for nonlinear optics, as they can confine light both spatially and temporally. However, a large number of nonlinear optical processes can occur in these systems, making it…
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…
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…
