ARC Grant Success

Members of the optical physics were successful in the recently announced round of ARC Grants. Rob Scholten was successful leading a new Linkage Project grant with Industry Partner MOGLabs: High-brightness wavelength tuneable lasers for quantum science.  Rob is also a co-CI with our colleague Andy Martin on a new Discovery Project Grant: Controlling spin coherence with rotation. Ann Roberts is a co-CI on a Linkage Infrastructure grant led by A/Professor Qiaoliang Bao at Monash University: Multi-functional 3D imaging system for micro and nanoscale devices. This grant will deliver important new tools for the Melbourne Centre for Nanofabrication.

Emil Wolf Outstanding Student Paper Prize

Congratulations to Faris Shahidan who was awarded an Emil Wolf Outstanding Student Paper Prize for his recent presentation, Towards Scalable Fabrication of Plasmonic Colour via Nanoimprint Lithography at OSA Frontiers in Optics in Washington DC! Faris also represented the University’s OSA student chapter at the associated student leadership conference. 

Attendees at the OSA Student Leadership Conference

Kelvin’s completion seminar

Zhe “Kelvin” Xu succesfully gave his PhD completion seminar to the School of Physics on 8 October. Kelvin (second from right) and advisory panel consisting of supervisors, Ken (right – main supervisor) and Ann (co-supervisor) and committee chair Lloyd Hollenberg (on left) are shown in the photo taken after the seminar.

Vivek, Jiajun and Jasper visit University of Manchester

Members of Ken’s team visited the University of Manchester from 1-5 October to make measurements in the laboratory of Dr Patrick Parkinson.  Jasper and Vivek gave presentations in the School of Physics and Astronomy.  In addition, all three had the opportunity to tour the National Graphene Insitute.

Paper in OSA Continuum

Work undertaken by Lukas, Kalpana and former MPhil student, Panji, has been published in OSA Continuum. The paper, Metasurfaces, dark modes, and high NA illumination, looks at the spatial dispersion of dark modes of metasurfaces consisting of an array of plasmonic radial trimers. Link to the paper here (open source).

Paper in Optics Letters

Led by Ben Craig, members of Ken’s group have co-authored a paper published on 13 September in Optics Letters, Experimental demonstration of infrared spectral reconstruction using plasmonic metasurfaces. Link to the paper here.

Student chapters @ Astrolight

Members of our OSA and SPIE student chapters, led by OSA Chapter President Faris Shahidan, once again hosted the ever-popular laser maze at the AstroLight Festival held at Scienceworks on the night of Saturday 8 September. There was a large contingent from the School of Physics (see photo) with telescopes, discussions on OzGrav and many other activities.

Optical information processing paper in JOSA A

Ann, Daniel Gomez and Tim Davis co-authored a paper, Optical image processing with metasurface dark modes, that was published today in Journal of the Optical Society of America A . The article looks at the use of the angular dependence of the excitation of certain ‘dark modes’ of metasurfaces to simulate edge enhancement of amplitude objects and visualisation of phase variations in an optical field. Ann’s gorgeous cat, Pi, features as a test object! The paper can be linked to here.

Crozier group publication in Nature Photonics

In collaboration with Ali Javey’s group at Berkeley, Ken and Vivek have coauthored a paper Polarization-resolved black phosphorus/molybdenum disulfide mid-wave infrared photodiodes with high detectivity at room temperature in Nature Photonics published on 27 August. The paper describes the investigation of black phosphorous (bP)/MoS2 heterojunction photodiodes as mid-wave infrared (MWIR) detector and it is shown that these devices can be competitive with conventional MWIR photodetectors. For more information see the original article.

Publication in ACS Nano

In work led by Heyou Zhang in Paul Mulvaney’s group in the School of Chemistry and the ARC Centre of Excellence for Exciton Science, Ann Roberts and former student Jasper Cadusch co-authored a paper published today in ACS Nano, Direct Assembly of Large Area Nanoparticle Arrays. This work looks at utilising template-directed electrophoretic assembly of gold nanoparticles.
