In a new paper in Optica, we demonstrate how radiative coupling between two nanowires gives rise to visible colours that can be tuned simply by changing their relative distance!

We have a challenging PhD position available in which we perform a joint project with the Coulais Lab: combining mechanical and nanophotonics metamaterials to realize mechanically-programmable optical metasurfaces! Find the full project description on the IoP website.

In our latest Nature Photonics paper we demonstrate how exciton resonances in monolayer 2D semiconductor can be used to realise large-area atomically-thin lenses with a tuneable intensity in the focus!

By coupling gap plasmons in aluminium plasmonic nanoparticle arrays with an ultra-thin layer of electrochromic WO3, we demonstrate how one can electrochemically tune the structural color of a completely solid-state device! Our results have recently been published in Nano Letters.

In our recent paper in Nature Communications we demonstrate a transparent photodetector with color and polarisation detection, by using a new type of optical resonance in silicon nanowire arrays!
