Optical frequency conversion in nonlinear dielectric metasurfaces. 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 ....Optical frequency conversion in nonlinear dielectric metasurfaces. 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
Metaphotonics and metasurfaces for disruptive sensing technologies. This project aims to address a big challenge in nanophotonics by developing revolutionary methods for efficient chiral sensing of molecules without the need for spectrometry, frequency scanning, or moving mechanical parts, and to enhance chiroptical signals a hundredfold with the help of metasurface structures.

This project aims to address a big challenge in nanophotonics by developing revolutionary methods for efficient chiral sensing of molecules without the need for spectrometry, frequency scanning, or moving mechanical parts, and to enhance chiroptical signals a hundredfold with the help of metasurface structures. Resonant metasurfaces are arrays of engineered dielectric nanoparticles with extraordinary characteristics, and they would allow to overcome current limitations of chiral sensing analytical tools. Detecting chiral molecules in low concentrations is crucially important to many fields of biology, chemistry, and pharmacy, as well as to the food and cosmetics industries, constituting a market of tens of billions of dollars.Read moreRead less

This project aims to develop and realise experimentally integrated circuits where light propagation mimics dynamics in arbitrarily complex imaginary photonic lattices. The project puts forward a universal and mass-fabrication compatible design concept of planar optical structures featuring unconventional synthetic multi-dimensional properties, which can also be reconfigured in real time. This underpins expected outcomes in optical detection with fundamentally enhanced sensitivity and optical signal switching with ultra-low threshold. The benefits of such breakthrough improvements can have broad applications spanning from future optical communication networks to optical sensors for monitoring and health applications.Read moreRead less

Summary
Disruptive nanotechnology to control light. The project aims to develop approaches to control propagation of light in nonreciprocal ways, similar to ways we control directions of electric currents with semiconductor diodes and transistors. Nonreciprocal behaviour of light is difficult to achieve, and it is currently limited to relatively large optical systems, which represents a road block for further miniaturisation and integration of optical devices. Expected outcomes of this project include f ....Disruptive nanotechnology to control light. The project aims to develop approaches to control propagation of light in nonreciprocal ways, similar to ways we control directions of electric currents with semiconductor diodes and transistors. Nonreciprocal behaviour of light is difficult to achieve, and it is currently limited to relatively large optical systems, which represents a road block for further miniaturisation and integration of optical devices. Expected outcomes of this project include first demonstrations of a radical miniaturisation of nonreciprocal optical components to the nanoscale. The outcomes should enrich our fundamental knowledge and assist the advancement of vital technologies such as integrated optical circuitry and communication infrastructure.Read moreRead less
