Description:
With proper design, the density of 2D optical storage can exceed that of 3D 
optical storage.

FULL STORY
======================================================================

In a groundbreaking study, researchers from Wuhan University and the State 
Key Laboratory of Water Resources and Hydropower Engineering Science have 
demonstrated the potential of Localized Surface Plasmon Resonance 
(LSPR)-based two-dimensional nanostructures for optical storage. 

The study, published in Optics Communications , provides another possibility 
for ultra-high density and high-resolution optical storage. 

Optical storage technology has been developing rapidly recently, with an 
increasing amount of research focusing on multi-dimensional high-density 
storage.While three-dimensional storage can achieve ultra-high-density 
optical storage by stacking two-dimensional storage layer by layer, it has 
limitations. These include high manufacturing costs, large processing errors, 
and complex readout processes. As a result, the implementation of 
two-dimensional ultra-high-density optical storage has become an area of 
great interest. Superior to Blu-ray 

The research team, led by Zhidan Lei, Dekun Yang, and Yiduo Xu, used 
'plasmonic technology' to realize ultra-high-density, low maintenance media, 
and long-life optical storage. They designed nano-scaled rotary gold square 
two-dimensional arrays to achieve ultra-high-density optical storage. 

For angle-resolved LSPR nano-arrays, when the rotation angle of a single unit 
gold square nano-structure is 2, the storage density was found to be 12.79 
GB/cm2. This is a staggering 53.29 times greater than that of a single-layer 
Blu-ray disc. The researchers found that by varying the shape and size of the 
nano-structure, even higher two-dimensional storage densities could be 
achieved. 

The findings of the study show that, with proper design, the density of 
two-dimensional optical storage can match or even exceed that of 
three-dimensional optical storage, potentially revolutionizing the way we 
store, archive and access data in the future. More from TechRadar Pro
