Innovators at Purdue University have created technology aimed at replacing Morse code with colored “digital characters” to modernize optical storage. He is confident that during and after the epidemic will help progress with the explosion of remote data storage.
Morse Code has been around since the 1830s. Familiar dots and dash systems can seem archaic given the information that is required to be digitally stored and rapidly accessed every day. But the same basic points and dashes are still used to aid storage in many optical media.
A new technology developed at Purdue aims to modernize optical digital storage technology. This advancement allows more data to be stored and read that data at an accelerated rate. The research is published in Laser and Photonics Review.
Instead of commonly using traditional dots and dashes in these techniques, Purdue innovators encode information in the angular position of small antennas, allowing them to store more data per unit area.
Alexander Mildisev, associate professor of electrical and computer engineering at Purdue’s College of Engineering, said, “The storage capacity increases greatly because it is defined only by the resolution of the sensor, by which you can determine the angular position of the antennas.” “We map the antenna angles to the colors, and the colors are decoded.”
The technology is aided in increasing the availability of storage space in optical digital storage technologies. Not all optical data storage media need to be laser-written or rewritten.
The majority of CDs, DVDs, and Blu-ray discs are “stamped” and not recordable. This class of optical media is an essential part of disposable cold storage with an instant access rate, long lasting shelf life, and excellent archival capabilities.
The manufacture of Blu-ray discs is based on the pressurization process, where the silicon stamper repeats the same dot-and-dash format that the final disc is receiving. A thin nickel coating is done to get a negative nickel. Blue-res, as well as DVDs and CDs, are only mass-produced.
“Our metasurface-based ‘optical storage’ is just like that,” said D Wang, a former Ph.D. Students preparing a prototype structure. “Whereas in our demo prototype, the information is ‘lit’ by electron-beam lithography, this can be replicated in the final product by a more scalable manufacturing process.”
This new development not only allows more information to be stored, but also increases the readout rate.
“You can put four sensors nearby, and each sensor will read its own polarization of light,” Kaldyshev said. “It helps increase the speed of reading of information compared to the use of single sensors with dots and dashes.”
Future applications of this technology include security tagging and cryptography. To develop these capabilities, the team seeks to partner with parties interested in the industry.
