演講摘要(Talk Abstract)
So far the optical data storage density is still limited by the diffraction of the beam. Recently a ground breaking multi-dimensional optical data storage, or so called polarization or spectral encoding, has lightened the way of Petabytes high density optical data storage of the next generation. The multi-dimensional optical data storage can multiplex the information in the additional physical dimensions of the writing beam, such as polarization state or excitation wavelength . T h e refore , the storage capacity can be greatly enhanced. Owing to their broad excitation and emission spectra tunability and large two-photon absorption sensitivity, semiconductor nanoparticles have been introduced for multi-dimensional optical data storage. In particular, the sharp polarization sensitivity of semiconductor quantum rods enables the polarization encoded photonic applications with less cross talks .

Dr. Li achieved his Ph.D degree in optics in 2009 at Centre for Micro-Photonics, Swinburne University of Technology. Now he is working on the multi-dimensional optical data storage project in Prof. Min Gu’s group at Centre for Micro-Photonics. His main research is focused on nanoparticlebased multi-dimensional optical data storage, including multi-dimensional encoding techniques and drive system, nanomaterials and nanophotonics .
