Abstract:Controlling the propagation of waves, such as light and sound, at the nanoscale is essential for advancing photonic and phononic technologies. Two distinct classes of nanostructured materials are investigated: ordered and disordered systems. Self-assembled monolayers of polystyrene nanospheres act as mechanical insulators, exhibiting phononic bandgaps in the gigahertz range. In contrast, disordered structures are explored for their random lasing behaviour. Cavity length, pump conditions, and mode coupling are analysed through theoretical modelling and experimental measurements to understand and control the spectral features of these complex systems. These results provide insights into wave manipulation in nanostructured media, with potential applications in sensing, communication, integrated optomechanical devices and neuromorphic computing.
