A new approach to in-plane surface plasmon polariton detection is demonstrated in a new article in Advanced Materials Technology by Dr Eugene Panchenko, other members of the group and collaborators at Tel Aviv University. The design is based on metal–semiconductor–metal photodetectors that are acknowledged as having one of the best speed characteristics among photodetectors. The technique has the potential to enable the integration of surface plasmons as signal carriers in future high-speed optoelectronic integrated circuits. More information here.
On 14 November, the 39th Session of the UNESCO General Conference proclaimed the date of May 16th as the International Day of Light. The proclamation of this annual International Day will enable global appreciation of the central role that light and light-based technologies play in the lives of the citizens of the world in areas of science, technology, culture, education, and sustainable development. For more info see lightday.org.
Congratulations to Dr Stuart Earl and Dr Eugene Panchenko who were awarded their degrees at the Sir Robert Menzies Oration on the 18th September.
Prospective Physics MSc students are invited to the optics group information session which will be conducted as a ‘walk and talk’ tour through the group’s laboratories in the Basement and on Level 5 of the David Caro Building. The tour will begin with a brief introduction to the group followed by a walk through our laboratories. There will be an opportunity for informal discussions with group members after the tour.
When: 12 noon Monday 16 October 2017
Where: Level 5 David Caro (Physics) Building
Representing our OSA Student Chapter at the 2017 Student Leadership Conference in Washington DC was a great experience for me. Meeting optics students from all over the world strongly motivated me to be an active member of the society – talking to someone in person makes all the difference. Out of the large range of fascinating talks, a discussion on not-so-linear career planning, lead by Carlos Lopez-Mariscal from Underwater Photonics, impressed me. I’m more than happy to share my insights and contacts with anyone interested!

Dr Alex Wood, Professor Robert Scholten are the authors of a new article, ‘Magnetic pseudo-fields in a rotating electron–nuclear spin system’ published in Nature Physics on 7 August. They used quantum sensors, nitrogen–vacancy (NV) centres, in a rapidly rotating diamond to detect pseudo-fields in the rotating frame to explore precession effects via quantum sensing. This defines a new approach to quantum control using rotationally induced nuclear spin-selective magnetic fields and provides an integral step towards realizing precision rotation sensing and quantum spin gyroscopes. The article can be linked from here. An interview with Dr Wood and A/Prof Andy Martin is available at the University of Melbourne Pursuit page.
Congratulations to Eugene Panchenko who completed his PhD studies. Eugene investigated new approaches for elucidating the properties of light. He demonstrated that optoelectronic devices combining metallic nanostructures and semiconducting materials can monitor guided electromagnetic waves or determine the polarisation states or colour of freely propagating light. His findings may enable new approaches to optical imaging, computing and communications.
We are delighted that Eugene is continuing in the group as a research fellow.
PhD student Lukas Wesemann was elected the new President of the University of Melbourne OSA student chapter at the AGM on 8 May. Hamid Soleimaninejad (Chemistry) was elected President of the local SPIE chapter.
Congratulations to Dene Murphy on completing requirements for his PhD! Dene used laser cooling of atoms to generate ultracold bunches of electrons and ions for nanoscale imaging. Through a combination of computer simulations and novel experiments his work enabled new insights into the charged particle interactions that limit the brightness of sources used in extreme electron and ion microscopy and nanofabrication.
