Microspectrometer paper published in Optica

Members of the Crozier group, led by Jasper Cadusch, have had their article ‘Silicon microspectrometer chip based on nanostructured fishnet photodetectors with tailored responsivities’ and machine learning published in Optica. In their article they describe using “fishnet pixels” to form a microspectrometer chip and demonstrate the reconstruction of four test spectra using a two-stage supervised machine-learning-based reconstruction algorithm.

Article in Physical Review Letters

Tim Davis and Ann Roberts,with collaborators Daniel Gomez (RMIT) and Fatima Eftekhari (MCN), have demonstrated asymmetric transfer functions in metasurfaces in research published in Physical Review Letters. The results reported set the direction for future developments of metasurfaces for optical signal processing. Full article can be found here.



Review in Advanced Optical Materials

Lukas Wesemann, Tim Davis, Jingchao Song and Ann Roberts contributed to the new review article ‘Plasmonic Near‐Complete Optical Absorption and Its Applications’ that was recently published in Advanced Optical Materials. It reports recent progress on the development of metasurfaces and thin film structures that produce strong absorption bands in the visible and longer wavelength regions of the electromagnetic spectrum, due in part to the excitation of plasmonic resonances. The article can be downloaded here.


New ACS Photonics publication

Group members Tim Davis and Ann Roberts are co-authors on a paper published in ACS Photonics on 22 January: Plasmene Metasurface Absorbers: Electromagnetic Hot Spots and Hot Carriers. The research, led by our collaborator Daniel Gomez (RMIT University) showed that a thin sheet of a tightly packed, self-assembled, two-dimensional lattice of metal nanoparticles, called plasmene, supported by a subwavelength dielectric film deposited on top of a mirror can be used in surface-enhanced spectroscopy and in the generation of plasmonic hot carriers.

Rob Scholten receives AOS John Love Award

At the 2018 AIP Congress, Professor Robert Scholten was announced as the 2018 recipient of the Australian Optical Society John Love Award which recognises those who have made a significant contribution to technical optics. The acknowledgement of Professor Scholten’s establishment of MOGlabs is well deserved.



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.
