Optical Data Storage Dips Below the Diffraction Limit
NEW YORK, Dec. 6, 2023 — Physicists at The City College of New York (CCNY) 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. “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 Tom Delord, postdoctoral research associate
