Physicists at The City College of New York have developed a technique with the potential to enhance optical data storage capacity in diamonds. This is possible by multiplexing the storage in the spectral domain. The research by Richard G. Monge and Tom Delord members of the Meriles Group in CCNY's Division of Science, is entitled "Reversible optical data storage below the diffraction limit" and appears in the journal Nature Nanotechnology.
"It means that we can store many different images at the same place in the diamond by using a laser of a slightly different color to store different information into different atoms in the same microscopic spots," said Delord, postdoctoral research associate at CCNY. "If this method can be applied to other materials or at room temperature, it could find its way to computing applications requiring high-capacity storage."
