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

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

This project aims to create multi-colour, ultrashort, highly coherent, bright pulses of soft X-rays based on high-harmonic generation in a table-top multiple-section gas cell. Studying multi-electronic and non-adiabatic processes and other fundamental aspects such as multi-electronic correlations and non-Born-Oppenheimer vibronic couplings in complex molecules is a major challenge in current ultrafast photochemistry research. This project will use multiple driving pulses with different carrier frequencies to control the spectral properties and time delay of the pulses. It will use the soft X-ray source to develop an ideal platform for studying multi-electronic and non-adiabatic processes, multi-electronic correlations and non-Born-Oppenheimer vibronic couplings in complex molecules. This is expected to advance materials science, paving the way to soft X-ray technologies.Read moreRead less

This project aims to develop the technology to connect superconducting quantum computers to the future quantum internet: an optical interconnect. Superconducting qubits are a leading quantum computing system, but their practical use is limited by their microwave operation frequency, as global quantum networks will operate at optical frequencies. This project aims to solve this problem by converting the microwave photons that carry superconducting quantum information to optical photons. To achieve high efficiency the project will investigate magnetically ordered rare-earth crystals, which uniquely possess the strong optical and microwave coupling required, to build a converter that could greatly enhance the capabilities of quantum computers.Read moreRead less
