Super-resolution in microscopy and optical recording. The classical resolution limit imposes severe restrictions on the performance of optical instruments, especially in optical microscopy and optical recording. Improved understanding of the fundamental principles involved in super-resolution should allow substantial increases in resolution to be achieved. We aim to explore theoretically and experimentally the performance of different super-resolution schemes alone and in combination, including ....Super-resolution in microscopy and optical recording. The classical resolution limit imposes severe restrictions on the performance of optical instruments, especially in optical microscopy and optical recording. Improved understanding of the fundamental principles involved in super-resolution should allow substantial increases in resolution to be achieved. We aim to explore theoretically and experimentally the performance of different super-resolution schemes alone and in combination, including optical masks, near-field optics, detector arrays, multi-photon imaging and digital deconvolution. Selected methods will be demonstrated with practical examples in multi-photon microscopy. Applications in super-high density optical recording will also be studied.Read moreRead less

Rogue waves in oceans and optical fibres. Rogue waves can sink large ships in the ocean. They appear more commonly than previously thought. Optical rogue waves, the laboratory counterparts of extreme ocean waves, will allow the project to study the main features of the phenomenon, provide the theoretical explanation for their existence and potentially help to eliminate these catastrophic events.
Engineering phase and the flow of light in nanophotonics. Optical devices on the scale of only billionths of a meter impel photonic revolution in information technologies. The extraordinary sensitivity and tunability of light confined on nano-scale is caused by the yet unexplored and poorly understood world of tiniest flows of energy, the optical vortices. In this project we will learn to manipulate optical vortices with the light itself, introducing original concepts for intelligent engineering ....Engineering phase and the flow of light in nanophotonics.

The extraordinary sensitivity and tunability of light confined on nano-scale is caused by the yet unexplored and poorly understood world of tiniest flows of energy, the optical vortices. In this project we will learn to manipulate optical vortices with the light itself, introducing original concepts for intelligent engineering of nano-elements of a photonic chip.

Exploding solitons. This project builds on previous work in which the existence of exploding solitons was confirmed. Explosions occur regularly in a variety of systems with continuous supply and dissipation of energy. Exploding solitons are more common than ordinary dissipative solitons and occupy large areas in the parameter space. They can be generated relatively easily, however the phenomenon is highly complex. This project aims to further understand exploding solitons so that the phenomeno ....Exploding solitons. This project builds on previous work in which the existence of exploding solitons was confirmed. Explosions occur regularly in a variety of systems with continuous supply and dissipation of energy. Exploding solitons are more common than ordinary dissipative solitons and occupy large areas in the parameter space. They can be generated relatively easily, however the phenomenon is highly complex. This project aims to further understand exploding solitons so that the phenomenon can be used for the generation of pulses with wide spectral output similar to `supercontinuum’ radiation. Research in this direction will provide the basis for building powerful laser sources with wide spectral output.Read moreRead less

Quantum effects in photosynthesis: responsible for highly efficient energy transfer or trivial coincidence? Understanding the precise details of the highly efficient energy transfer processes in photosynthesis has the potential to impact the design of efficient solar energy solutions. This project will gain this understanding by exploring the nature of interactions between different components and the significance of quantum mechanics.

This project aims to develop a new generation of bright, laser-like x-ray sources for laboratory use. X-ray sources underpin key diagnostic techniques in materials science, advancing applications from structural engineering through to ore processing and energy storage. However, the limited brightness of present-day laboratory x-ray sources restricts the utility and range of these diagnostic techniques. This research intends to use intense lasers to create microscopic plasmas and drive high harmonic generation. The high harmonic generation process is already used to create laser-like ultraviolet light. By optimising the characteristics of the plasma medium, the project aims to extend bright high harmonic generation to the x-ray regime.Read moreRead less

Summary
Brillouin microscopy for high-speed imaging of rigidity within cells. This project aims to improve the sensitivity and speed of Brillouin microscopes. Brillouin microscopes use light to measure the stiffness of samples in 3D without requiring physical access, allowing their use in inaccessible locations such as the interior of cells or within intact tissue. However, Brillouin microscopes are too slow to be used in most research. This project introduces a new approach based on different optical p ....Brillouin microscopy for high-speed imaging of rigidity within cells. This project aims to improve the sensitivity and speed of Brillouin microscopes. Brillouin microscopes use light to measure the stiffness of samples in 3D without requiring physical access, allowing their use in inaccessible locations such as the interior of cells or within intact tissue. However, Brillouin microscopes are too slow to be used in most research. This project introduces a new approach based on different optical physics that is expected to enable faster and more precise imaging. The microscope will be used to study the movement of amoeba, where it is expected to reveal the controlled stiffening and fluidising of the different regions of protoplasm believed to underlie the cell mobility.Read moreRead less
