New nanostructured glass for imaging and recording
Date:8/18/2011

University of Southampton researchers have developed new nano-structured glass, turning it into new type of computer memory, which has applications in optical manipulation and will significantly reduce the cost of medical imaging.

In a paper entitled Radially polarized optical vortex converter created by femtosecond laser nanostructuring of glass published in Applied Physics Letters, a team led by Professor Peter Kazansky at the University's Optoelectronics Research Centre, describe how they have used nano-structures to develop new monolithic glass space-variant polarisation converters. These millimetre-sized devices change the way light travels through glass, generating 'whirlpools' of light that can then be read in much the same way as data in optical fibres. This enables more precise laser material processing, optical manipulation of atom-sized objects, ultra-high resolution imaging and potentially, table-top particle accelerators. Information can be written, wiped and rewritten into the molecular structure of the glass using a laser.

According to the researchers, at sufficient intensities, ultra-short laser pulses can be used to imprint tiny dots (like 3D pixels) called 'voxels' in glass. Their previous research showed that lasers with fixed polarisation produce voxels consisting of a periodic arrangement of ultra-thin (tens of nanometers) planes. By passing polarised light through such a voxel imprinted in silica glass, the researchers observed that it travels differently depending on the polarisation orientation of the light. This 'form birefringence' phenomenon is the basis of their new polarisation converter.

The advantage of this approach over existing methods for microscopy is that it is 20 times cheaper and it is compact.

"Before this we had to use a spatial light modulator based on liquid crystal which cost about 20,000," said Professor Peter Kazansky. "Instead we have just put a tiny device into the optical b
