DVD plus nano-rods equals security, density: researchers
Swinburne and Taiwanese researchers have demonstrated technology that can use a single laser beam to create 3D polarization in nanomaterials.
What’s cool about this is that they demonstrate that the polarization can be used to encrypt information – as well as expanding the storage capacity of optical media like DVDs.
