Light energy storage medium

Can light be used as a data storage medium?

Novel applications are outlined, concluding with the scaling challenges to be addressed toward allowing light to serve as both a data-carrying and data-storage medium. Integrated optical memory technologies may in the future become an attractive option for storing data in an energy efficient and compact manner.

What are light-assisted energy storage devices?

Light-assisted energy storage devices thus provide a potential way to utilize sunlight at a large scale that is both affordable and limitless.

Do light-assisted energy storage devices have a bottleneck?

After the detailed demonstration of some photo-assisted energy storage devices examples, the bottleneck of such light-assisted energy storage devices is discussed and the prospects of the light-assisted rechargeable devices are further outlined. The authors declare no conflict of interest.

How long can a solid state device store light coherently?

A solid-state device can now store light coherently for up to one minute. Figure 1:(a) Energy-level scheme for EIT experiments: two ground states ( | g 〉 and | s 〉) are connected to one excited state ( | e 〉) by an optical transition. To reach the EIT condition, the frequency difference between the input and control beams must be equal to ...

How can a large-area processable light source improve optical energy density?

To address this issue, large-area processable light sources (e.g., line beam lasers, and flash lamps) along with optical beam shaping technologies can be introduced to enable required optical energy density over broad surfaces without sacrificing process quality and precision.

Are integrated optical memory technologies the future of data storage?

Integrated optical memory technologies may in the future become an attractive option for storing data in an energy efficient and compact manner. The progress that has been made in the field has now been reviewed by three Greek researchers.
