A Presentation on new developments in Authentix’ sub-wavelength nano-optic platform, KolourOptik, and lessons learned in industrializing this technology for mass manufacturing in various applications, including banknote, ID, and brand security features.  Developments discussed include mixing colours, colour shifts/switches, and programmable animations using plasmonic pixels.   

These new optically variable features have been achieved through improvements in photonic modelling to increase surface plasmonic resonance efficiency and software optimization.  Furthermore, Authentix has employed advanced metrology techniques to precisely measure the fidelity of each plasmonic nanostructure during every step of the process from origination through to the final manufactured device and to generate originations which compensate for losses during the process.   

These measurements and their impacts on performance of plasmonic pixel sets will be discussed as well as some lessons learned in our experience industrializing deep sub-wavelength nano-optical structures.  Also covered will be how this industrialization could open the doorway for other potential metamaterial-based nanostructures such as meta-lenses, emerging trends in optical document security, and the integration of digital security features.
