Scientists are harnessing quantum phenomena to develop a new generation of optical memory with enhanced durability, speed, and efficiency.
To overcome the limitations of current optical storage, the new method uses rare-earth emitters with varying wavelengths to increase data storage capacity.Researchers from the US Department of Energy’s Argonne National Laboratory and the University of Chicago Pritzker School of Molecular Engineering have proposed a new method for optical memory storage.
“We worked out the basic physics behind how the transfer of energy between defects could underlie an incredibly efficient optical storage method,” stated Giulia Galli, an Argonne senior scientist and Liew Family Professor at PME.Considering the current increasing volume of digital data worldwide, there has been a continuous demand for innovative storage technologies.
By using different wavelengths of light for each emitter, known as wavelength multiplexing, more data could potentially be stored in the same area, stated the researchers.The researchers created models of materials with narrow band rare-earth emitters to test their approach. These materials have atoms that absorb and emit light at very specific, narrow wavelengths of light, which can then be captured by nearby quantum defects.
