Green Photonics

The green photonics project is focused on the development of nanoparticle based high performance and efficient optical data storage and display technologies. As demand for high definition video and television increases, so does the amount of storage and size of displays. Incorporating nanoparticles into these devices can allow for the technologies to expand with society's demand, whilst maintaining a small environmental footprint.

Research Overview:

The development of novel optically based devices is seen as a key step towards next generation information technology due to the potential for faster, simpler and more energy efficient operation. In particular, optically based information storage devices have been identified as potential candidates for the replacement of their electronic counterparts owing to their intriguing properties such as high capacity, fast speed, high sensitivity and high resistance to strong electro-magnetic radiation. The development of new lighting technologies based on nanoparticles also offers promise for high quality and efficient illumination for display technologies such as 3D TV. The green photonics project aims to investigate the use of optics and nanoparticles in these key areas to develop and demonstrate efficient and advanced devices that play a central role in modern lifestyles.

Optical Data Storage

Optical data storage is an important field that has been pioneering the technical evolution in information technologies. The amount of information generated every year is increasing dramatically and according to the IDC, there is 6-fold increase in data every four years. The urgent demand compels the development of Petabytes disc technology. One of the main tasks of the green photonics project is to develop a multi-dimensional optical data storage device including the multi-dimensional recording- and reading-enabled drives and optical discs. Nanoparticle's with sharp polarization and spectral sensitivity will be dispersed in optical discs. The multi-dimensional optical data storage employs the additional physical dimensions such as polarization and spectra of the writing beam to multiplex information, which can enhance the storage capacity by orders of magnitude. In particular, the superresolution recording technique will be enabled in the targeted drive system. Therefore, the ultimate goal of the multi-dimensional optical data storage is aiming for Petabytes/disc. If successful, this technology will underpin every corner of our modern life such as e-banking, e-education and e-medicine

Display Technologies

Another important subset in the information technology chain is optical display technologies. There is a tremendous worldwide interest in high resolution, fast, high-definition three-dimensional (3D) display devices. Activating nanoparticles in photorefractive polymers for high efficient photosensitization will enable 3D display devices with fast response, wide viewing angle and high resolution.



Besides the application in 3D display, the activated nanoparticles can also underpin other cross disciplines such as photovoltaics and LEDs which are growing in popularity and would benefit from higher efficiencies.
