New article on optical nanotweezers designed by computer algorithm

Neuton’s paper on algorithm-designed plasmonic apertures for optical nanotweezers has been published in Advanced Optical Materials. The apertures were fabricated using a helium ion microscope and were characterised by cathodoluminescence and optical trapping experiments. It was shown that at every laser intensity, an algorithm-designed structure can outperform a conventional plasmonic aperture.

Lukas Wesemann PhD completion

Congratulations to Lukas Wesemann who was awarded his PhD on 5 March. His citation states that he investigated all-optical image processing with nanostructures.  He demonstrated both thin-film and patterned surfaces that can detect the edges of features in an image or permit visualisation of transparent objects. His study will enable the development of ultracompact and energy-efficient optical systems for applications, including in biotechnology and remote sensing. Dr Wesemann is continuing research into meta-optical devices and systems.

Research Fellow positions in Meta-Optics available

Ken Crozier and Ann Roberts have two research fellow positions available for suitably qualified applicants. The positions will be part of the ARC Centre of Excellence for Transformative Meta-Optical Systems and the roles will involve working on the experimental realisation of new nano-optical devices and their incorporation into optical systems. Applications close on 16 March. More information including position descriptions and a link to the application form here.

TMOS recruiting MSc and PhD students now!

The ARC Centre of Excellence for Transformative Meta-Optical Systems is now seeking expressions of interest from suitably qualified candidates for MSc and PhD positions. If you are interested in joining the Melbourne node as either a PhD or MSc student contact Professor Ken Crozier or Professor Ann Roberts. Note that PhD applications must be received by 31 October for Australian domestic students to have the best chance of attracting a scholarship.

Detecting the Rotation of a Quantum Spin

Alex Wood and Rob Scholten have co-authored a new paper in Physical Review Letters, highlighted in Physics Focus, that is generating a lot of excitement. Their experiments demonstrate the fundamental connections between spin, physical rotation, and quantum phase, and are applicable in schemes where the rotational degree of freedom of a quantum system is not fixed, such as spin-based rotation sensors and trapped nanoparticles containing spins.
