Photonic crystals have recently became very attractive for photonic technology, that uses light instead of slow electrons as the information carriers replacing electronics in communications and information management. This project has the purpose to develop the fundamental concept of nonlinear photonic crystals and demonstrate their possible applications analysing the properties of the nonlinearity-induced light localization, nonlinear transmission, and frequency conversion in band-gap materials with the intensity-dependent optical response. This will allow the possibility realising in practice nonlinear switching even for sharply bent waveguides, providing an effective way to control the flow of light in band-gap photonic circuits.Read moreRead less

Dynamic Mechano-Microscopy for use in Mechanobiology . We will develop an innovative microscope that will enable new discoveries in biology. Most microscopes form images of a sample's optical properties, instead we will image a sample's mechanical properties. The reason our novel approach is needed is that cell behaviour depends on the stiffness of it's environment, but current microscopes are unable to image this. Our microscope will provide insights in biology that can improve our understandi ....Dynamic Mechano-Microscopy for use in Mechanobiology .

The reason our novel approach is needed is that cell behaviour depends on the stiffness of it's environment, but current microscopes are unable to image this. Our microscope will provide insights in biology that can improve our understanding of cells, the building blocks of life. We will achieve this by: 1. Developing a microscope that combines microscopic resolution with rapid imaging; 2: Developing the capability to image both within the cell and its surrounding environment; and 3. Using our microscope to make discoveries in biology.Read moreRead less

Dissipative soliton resonances and their applications. Many branches of science and technology, such as precise eye surgery, biological cell machinery, painless dentistry, optical data storage, material micro-machining and laser fusion, rely heavily on high power femtosecond pulse laser oscillators that deliver the necessary power, in a very short time, to nanometer scale targets within a tissue or a material.

Many branches of science and technology, such as precise eye surgery, biological cell machinery, painless dentistry, optical data storage, material micro-machining and laser fusion, rely heavily on high power femtosecond pulse laser oscillators that deliver the necessary power, in a very short time, to nanometer scale targets within a tissue or a material. A further increase in the power of a pulse and a decrease in its duration, combined with a reduction in complexity and price can be achieved, but this advance depends strongly on the theory of dissipative solitons, and particularly on the idea of soliton resonances. Novel ideas developed within this project will put new productive tools in the hands of doctors, biologists and physicists.Read moreRead less

Photovoltaic (PV) devices convert sunlight directly into electricity. For decades, the dominant PV technology has been based on thick, costly silicon wafers. However, due to higher energy conversion efficiencies and manufacturing processes, thin film PV cells can provide lower price than of the conventional wafer-based technologies. This project takes one of the leading thin film technologies and couples it with a passive optical layer, which will result in a 30% performance enhancement by overcoming internal absorption losses. It is anticipated that the increased performance will enable the thin film PV technology to be far more commercially viable and attractive for future commercialisation, and hence reduce the cost of solar power.Read moreRead less
