In work just published in Nature Communications, a collaboration between University of Melbourne, CUNY, and RMIT University has demonstrated a metasurface that can be switched between edge detection and producing a conventional image. The device integrates a thin film of VO2 that undergoes a phase change at around 68C altering its optical properties opening up […]

Work led by Tim Davis is featured as an Editor’s Pick in the latest Optics Express – link here. We show that by extracting structural information from transmission electron microscopy data, including characteristic disorder parameters, good agreement with spectral specular and non-specular reflectance measurements can be obtained.

In work just published in Materials Today Advances, members of the group, led by Laura Ospina-Rozo, report new results into the optical and near-infrared properties of beetle elytra. We showed that some scarab beetles use composite, non-chiral structures to reflect light where the elytra consist of a broadband reflective structure overlain by a green filter. […]

A new paper led by PhD student Niken Priscilla reveals an intriguing device which exhibits a different colour variation when observed from either side. Unlike previous research the structure involves four simple nanoscale thickness layers of silica, silver and chromium. The research has been published in Advanced Photonics Research – link here.
