This project aims to investigate the mixing of light colours in semiconductor nanocrystals arranged in an ultra-thin transparent film, called a nonlinear metasurface. Understanding of the resonant nonlinear interactions in such metasurfaces will allow for the up and down frequency conversion of light beams and images with efficiencies well beyond current capabilities. The outcomes of the project will form the basis for novel cost-effective and compact devices for infrared imaging, and will also enable ultra-fast sources of quantum light with tailored spatial and spectral correlations. These will benefit important applications in defence and security, including night vision, security holograms, quantum cryptography and communications.Read moreRead less
