Publication highlights

My research is concentrated on engineering nano-partciles to manipulate light-materials interactions and generate new class of nanoscale surfaces (metasurfaces). Our metasurfaces have a wide range of applications including, but not limited to:

Night vision: Our ultra-thin metasurface film made of AlGaAs crystals was employed to convert light frequencies directly from infrared to visible. The use of such optical process for frequency conversion eliminates the need for a transition from the optical to the electronic domain and allows for ultimate miniaturisation of the night vision devices. This is a key innovation, patented by the ANU, which was considered impossible just a few years ago (see Video here). 

Ultra-sensitive detectors: We have developed a novel sensor, comprising of tailored fractals of dielectric TiO2 nanoparticles on a resonant metallic metasurface. Such a hybrid metasurface allows for enhancing the interaction of the optical near-field with a gaseous environment and also significantly increases the active area for gas condensation. We demonstrated how an optimal metasurface is able to detect refractive index changes lower than 8x10-6 in a gas mixture, a new world record, achieving selective detection of gas molecules with outstanding sensitivity of 137345 nm/RIU. This unique sensor can be applied for contactless non-invasive medical sensing, through detection of ultra-low concentrations of biomarkers expelled by the body through the breath (see Video here).
