The study, published inOptics Communications, provides another possibility for ultra-high density and high-resolution optical 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.
They designed nano-scaled rotary gold square two-dimensional arrays to achieve ultra-high-density optical storage.
This is a staggering 53.29 times greater than that of a single-layer Blu-ray disc.
