Recently, researchers at the City University of New York (CUNY) have successfully used small nitrogen defects in diamond's atomic structure as "color centers" to write data for storage (and then retrieval). The technique, published in Nature Nanotechnology , allows multiple bytes of data to be written into the same nitrogen defect by encoding the data into multiple light frequencies (i.e. colors) - which can be done without obfuscating the information content. completed.
The technology can store multiple bits of data in diamond flaws, achieving a data density of 25GB per square inch by encoding on different light frequencies. The technology exploits nitrogen defects in diamonds, which act as color centers to store information by precisely controlling their charge. The researchers used narrow-band lasers and cryogenic conditions to control the charge at these color centers very precisely and could write and read at the level of individual atoms.
They showed how to print multiple colors within the same nitrogen defect using appropriate diffraction limits for each color, meaning that as many bits as possible can be built based on the number of colors the atoms are individually programmed with.
A unique feature of this technology is that it is reversible and can be written, erased and rewritten an unlimited number of times. Additionally, it circumvents the diffraction limit, which can be achieved by exploiting the slight color (wavelength) changes that exist between color centers that are closer than the diffraction limit.
This research has important implications for improving optical data storage capacity, especially in computing applications that require high-capacity storage. While cryogenic cooling is currently required to operate these color centers, the researchers are confident that their technology can operate at room temperature and may one day lead to improved storage at lower energy costs.
