Holograms were designed more than 65 years ago by the physicist Dennis Gabor and holographic techniques, despite becoming popular with the passage of time, have advanced on very diverse fronts such as microwave holography (used in radar systems) or holograms acoustic (used in seismic applications). Now, thanks to a new study, holograms are much closer to ordinary people.
A team of researchers from the University of California at Riverside has created a new type of holographic memory device capable of significantly improving the storage-level limitations of current electronic devices.
Holographic memory or holographic data storage differs from traditional systems in that holographic memory can read data in parallel , and traditional ones have access to data in a linear manner. Thus, it is capable of storing multiple images in the same area using different light and angles.
The new type of memory device uses spin waves (or magnons) instead of optical rays. These spin waves are compatible with conventional electronic devices and can operate at a shorter wavelength than optical devices, thus allowing small gadgets to have greater storage capacity.
The results obtained show that it is completely feasible to apply holographic techniques on magnetic structures to create a holographic memory device , thus opening a new field of research, which can have a tremendous impact on the development of electronic devices for mass use.
The study has been featured in the journal Applied Physics Letters .
