Multidimensional Optical Data Storage

In Multidimensional optical data storage project, we aim to demonstrate multidimensional recording/reading of data with plasmonic nanostructure based materials where the spectral and polarisation properties add additional dimensions to current 2D and 3D recording mechanisms. The new dimensions multiply storage limits without increasing the physical size of the medium.


Project Overview:

Aim:
This project aims to develop a new concept of multi-dimensional optical data storage using plasmonic nanostructures. We aim to lay the foundation to reach the data density of Petabyte per disk space (200,000 times the information in a current DVD)

Research Overview:

In the consumer data storage market, the need for faster and high capacity optical storage systems is ever growing, and the current technology of reducing the written bit size to increase data capacity is already approaching its limit imposed by resolution limit of light.

The Centre for Micro-Photonics has devoted a large research effort to overcome the problem and successfully demonstrated ~ 1.1 Tbits / cm3 by recording data bits in five dimension using plasmonic gold nanorods. This was made possible by introducing spectrum and polarization dimensions to the recording.

We also recently demonstrated successfully the multilayer recording and readout using electron beam lithographed gold nanorods. In this we used detuned surface plasmon readout scheme to read deeper layers of information with continuous wave laser. This scheme is
