In nonlinear optics, we always have a trade-off present, where a stronger desired nonlinear response, e.g. a phase shift is also accompanied by one or more undesired nonlinear effects, such as additional absorption.…
The nanophotonics group has some big news. After a very succesfull and enjoyable 6 years at the University of St Andrews, the group…
One of the key trade-offs in optics is that the higher the resolution of a spectrometer, the greater the footprint that it needs. However,…
Together with Patrick Sebbah from the Bar-Ilan University, we have made an important advancement in the development of tunable random…
Silicon photonics, the use of light to transmit and process information, has become increasingly popular over the last few years due to its high data transmission rates and compatibility with existing integrated…
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…
