This project aims to develop a breakthrough all-optical approach to create micro-domain patterns in nonlinear optical media using tightly focused femtosecond pulses. It will lead to the first flexible all-optically formed quasi-phase matched structures, enabling access to a broad range of applications for exceptional control over both photons and phonons.

Experimental and theoretical work on the development of novel nano-structured materials with unusual optical properties. Special attention to our research is the development of tunable and functional photonic metamaterials with unusual properties. Of particular interest are the development of ultra-thin metasurfaces with high sensitivity to light intensity.

In order to build a random number generator, we need to estimate the amount of randomness it has. Our aim to estimate the min-entropy of a finite sample of data using the Bayesian and Frequencist estimators.

This project aims to investigate the concepts and strategies required to produce electrically injected semiconductor nanowire lasers by understanding light interaction in nanowires, designing appropriate structures to inject current, engineer the optical profile and developing nano-fabrication technologies. Electrically operated nanowire lasers would enable practical applications in nanophotonics.

Dissipative solitons are generated due to the balance between gain and loss of energy as well as to the balance between input and output of matter. Their existence requires continuous supply of energy and matter that is available in open systems. The model explains variety of phanomena in biology and physics.

Terahertz frequency range is the least explored part of the electromagnetic spectrum, and we work towards using it in a range of breakthrough imaghing, security and communication applications. We offer a range of Honours, Masters and PhD projects, which include theoretical, numerical and experimental work with terahertz metamaterials.

The project aims to investigate compound semiconductor micro-ring lasers on silicon substrates using selective area growth to engineer the shape of the lasing cavity at the nano/micro-scale. This project will open up new doors to the industry since an integrated laser which is reliable, efficient and easily manufacturable is still elusive in Si photonics.

Recent advances in laser technology now enable the combination of multiple high-quality lasers into a single high-power beam. The aim of this project is to investigate such `coherently-combined' laser systems within the context of Earth-to-Space laser transmission. Applications of this technology include satellite laser ranging, clock transfer and free-space optical communications, and space debris tracking and remote manouevring.

Antennas are at the heart of modern radio and microwave frequency communications technologies. They are the front-ends in satellites, cell-phones, laptops and other devices that make communication by sending and receiving radio waves.
