TMOS launched!

Members of the Melbourne node, Dr Wendy Lee, Dr Lukas Wesemann and PhD student Shaban Sulejman attended the official launch of the ARC Centre of Excellence for Transformative Meta-Optical Systems (TMOS) at ANU on the 28th September. The launch was attended by Australian Research Council Chief Executive Officer Ms Judith Zielke, ANU Vice Chancellor Prof. Brian Schmidt in attendance and ANU Chancellor Julie Bishop in attendance.


TMOS seeking new PhD students for 2023 commencement

The Australian Research Council Centre of Excellence for Transformative Meta-optical Systems (TMOS) is currently seeking expressions of interest from prospective PhD students. More information here. Applications can be submitted through the EOI form or directly to supervisors. For students interested in studies at Melbourne under the supervision of Professor Ken Crozier and/or Professor Ann Roberts, a list of projects can be found here. Note that international students need to submit applications to the University of Melbourne before the 30 September to be considered in the first round for 2023 so prospective supervisors need to be contacted well before then.



New research reveals colour flip

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.

Alex Wood awarded Woodward Medal

Dr Alexander Wood is the recipient of the 2021 Woodward Medal in Science and Technology for his suite of publications in Nature Physics, Science Advances and Physical Review Letters concerning how physical rotation can be used as a tool for control and measurement of a quantum system. The Woodward Medal was established to reward outstanding and original scholarship. Congratulations, Alex!


New paper on polarisation-insensitive, scalable plasmonic colouration

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 prospects for applications in manufacturing and elsewhere. Link to paper (open access) here.


Congratulations to Dr Faris Shahidan

Congratulations to Dr Shahidan whose PhD was awarded on 31 August! From his citation his contributions to the field involved the investigation of novel approaches to generating nanostructured surface colouration. He showed that nanoimprint lithography can produce complex three-dimensional nanostructures over large areas and at scale critical to adoption of structural colour technologies. His work underpins new approaches for producing environmentally conscious colour films for consumer goods and next-generation security features.

TMOS seeking PhD and masters students

The ARC Centre of Excellence for Transformative Meta-Optical Systems is now seeking expressions of interest from suitably qualified candidates for MSc (coursework) and PhD positions. By harnessing the disruptive concept of meta-optics TMOS will develop the next generation of ultra-compact optical systems with fundamentally new and exciting capabilities.

If you are interested in joining the Melbourne node in 2022 as either a PhD or MSc student contact Professor Ken Crozier or Professor Ann Roberts.

Actively variable-spectrum optoelectronics with black phosphorus

Nima Azar, Sivacarendran Balendhran and Ken Crozier are co-authors on a Nature paper with colleagues from the University of California at Berkeley and the Lawrence Berkeley National Lab. They made use of the extraordinary sensitivity of the bandgap of black phosphorous (bP) to strain to show the continuous and reversible tuning of the operating wavelengths in bP light-emitting diodes and photodetectors.
