optical memory

[′äp·tə·kəl ′mem·rē]
(computer science)
A computer memory that uses optical techniques which generally involve an addressable laser beam, a storage medium which responds to the beam for writing and sometimes for erasing, and a detector which reacts to the altered character of the medium when it uses the beam to read out stored data.

Optical bistability and multistability devices are widely used in the areas of optoelectronics such as optical memory, optical transistor, all-optical logic gate, and all-optical switching due to their ability of harnessing optical nonlinear characteristics [1-4].
The workshop discusses optical memory and how it affects emotional memory for actors who see a lot of viewers that are imprinted on their memories.
Photonic crystal is a platform which provides a comfort zone to design the logic gates, by the way many applications are available such as optical memory devices, optical computing units, processors, and controllers.
Integral to a functioning quantum network is a quantum optical memory (QM), a device allowing for the faithful storage and recall of quantum states of light using a strong and controllable light-matter interaction.
'This is the first ever truly non-volatile integrated optical memory device to be created,' explains Clarendon Scholar and DPhil student Carlos Rcos, one of the two lead authors of the paper.
For her part, Minister of Culture Lubanah Mshaweh said that the gallery is considered an optical memory and documentation of human tragedy.
With a new type of optical storage, it might be possible to store 360 terabytes for one million years on a DVD-sized optical memory. The technique uses glass as a medium and recorded information in 5D, but could eliminate both issues of longevity of data storage and also the amount of data that can be stored.
Organic photochromic compounds are one kind of candidates for optical memory (8), (9), especially for rewritable optical memory.
This section overviews some typical problems or challenges that have concerned telecommunication engineers for a long time, such as optical issues, limited number of available wavelengths, lack of optical memory, and electronic vs.
