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.

The Australian Research Council Centre of Excellence for Transformative Meta-optical Systems (TMOS) is currently seeking expressions of interest from prospective PhD research higher degree and MSc coursework students. Students should send an expression of interest to Professor Ken Crozier and/or Professor Ann Roberts – a list of potential projects can be found here. Applications need […]

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.

Faris Shahidan has led new work appearing today in Optics Express. Using nanoimprint lithography we show that it is possible to generate vivid colouration without the requirement for polarised light. Embossed polymers are coated with a variety of metals permitting an investigation of the role of the choice of metal. This work opens up the […]
