Terahertz imaging through emissivity control
Michal Mrnka, Harry Penketh, Ian R. Hooper +5
Adoption of terahertz technologies is hindered by the lack of cost-effective THz sources. Here we demonstrate a fundamentally new way to generate and control THz radiation, via spa…
High-harmonic generation enhancement with graphene heterostructures
Irati Alonso Calafell, Lee A. Rozema, Alessandro Trenti +9
We investigate high-harmonic generation in graphene heterostructures consisting of metallic nanoribbons separated from a graphene sheet by either a few-nanometer layer of aluminum…
Space-squeezing optics in the microwave spectral region
Michal Mrnka, Euan Hendry, Jaroslav Láčík +4
Optical systems often consist largely of empty space, as diffraction effects that occur through free-space propagation can be crucial to their function. Contracting these voids off…
Spatiotemporal refraction of light in an epsilon-near-zero ITO layer
Justus Bohn, Ting Shan Luk, Euan Hendry
When light travels through a medium in which the refractive index is rapidly changing with time, the light will undergo a shift in its frequency. Large frequency shifting effects h…
Total internal reflection based super-resolution imaging for sub-IR frequencies
Lauren E. Barr, Peter Karlsen, Samuel M. Hornett +5
For measurements designed to accurately determine layer thickness, there is a natural trade-off between sensitivity to optical thickness and lateral resolution due to the angular r…
Approximations used in the analysis of signals in pump-probe spectroscopy
Peter Karlsen, Euan Hendry
In pump-probe spectroscopy, one often needs to analyse the transmission or reflection of electromagnetic waves through optically pumped media. Here, it is common practice to approx…
