Title: Ultralight Energy Saving Structural Color Paint
Abstract: The talk will outline an approach to structural coloration that exploits the plasmonic resonances that arise naturally from the interaction of light with a random array of metallic islands at visible frequencies. These self-assembled nanoislands, grown using conventional thin film techniques, are placed near a mirror to create a strong hybridization of localized plasmon and subwavelength cavity modes. This results in a single resonance with minimal angular and polarization dispersion and over 90% reflectance at certain wavelengths. Crucially, the optical response of these nanostructures can be easily adjusted across the entire visible spectrum through simple changes in geometrical parameters to achieve a full color range. Fabricating the structures through large-scale techniques we produce stand-alone paints that are ready to be transferred onto any substrate. Remarkably, the platform offers full coloration with a single layer of pigment, with an unbeatable surface density of 0.4 g/m2, making it the lightest paint in the world. Overall, our plasmonic structural color provides a non-toxic, fade-resistant, and environmentally friendly coloring solution that bridges the gap from proof-of-concept to real-world industrial applications.

Title: Malaysia’s First Oil and Gas Enterprise 5G Deployment : A Success Story
Abstract: 5G technology is the most advanced cellular last-mile technology that has the superiority to deliver high bandwidth data speeds, ultra-low latency and massive network capacity. 5G usage will provide a remarkable technical leap advantages as compared to the 4G and Wi-Fi technology which are currently being deployed across PETRONAS. With 5G technology are readily available, all the current use cases and applications supported by 4G and Wi-Fi will be enhanced with better user experiences and future proof infrastructures. 5G will even speed-up the adoption of IIoT which are crucial in supporting bigger digitalization agendas such as Digital Twin, Artificial Intelligence and Machine Learning. Whilst 5G technology are ready to be deployed, the lack of 5G use cases could potentially hamper the 5G deployment pace. The Oil and Gas end users are still looking for more use cases to be readily available in the market to justify the 5G technology deployment. While Oil and Gas companies may aim for its individual 5G site deployment, collaboration between oil and gas
companies, technology solution providers, 5G chipmakers, telecommunication service providers, universities and related government agencies are keys in expediting 5G solutioning’s time to market. This would spur the development of 5G-enabled IIoT solutions and Use Cases. Our drive is for the technology to be deployed at faster pace to reap the benefit of 5G technology, upholding the digitally enabled operation aspirations and improve business performances.

Title: Smart Materials for Photonics: Vanadium Dioxide
Abstract: Vanadium dioxide (VO2) is a “smart” material that exhibits a reversible metal–insulator transition (MIT) at 68 °C (341 K) between a semiconducting low-temperature phase and a metallic high-temperature phase. This transformation is accompanied by a structural phase transition from the ground-state monoclinic (M) to a tetragonal phase (R). In addition to these changes in the electronic and structural properties of the material, the transmittance for infrared (IR), near-infrared (NIR) and terahertz (THz) radiation significantly decreases between the M and R phase, which makes VO2 attractive for ultrafast photonic devices, thermochromic smart windows and smart radiator devices. The MIT properties of VO2, including the transition temperature and the transmittance contrast, can be efficiently tailored through doping with an appropriate concentration of donors and/or acceptors and through a proper control of crystallinity, morphology and stoichiometry of the VO2 films. In this presentation, we will review our recent achievements on the synthesis, characterization and applications of undoped and doped VO2 films.

Title: Applications of nonlinear optics for modelocking of fibre lasers and novel distributed fibre sensing schemes
Abstract: In this talk I will present recent work from my group looking at the use of nonlinear optics for sensing. This work falls into two main categories. Firstly we have looked at using both Brilliouin scattering and Raman scattering to make distributed temperature and strain measurements along a fibre running through the alpine fault in southern NZ. This allows us monitor the fault in real time and can provide useful information for geophysicists. Next we have made progress in using surface enhanced Raman scattering for disease detection. This work has relied on femtosecond laser machining of the gold substrates producing periodic structures with precise curvatures to enhance the Raman signal along with machine learning to classify the resulting spectra. Finally I will discuss possible future applications of this work with an emphasis on optical sensing in remote and hostile environments.
