Optical computing or photonic computing uses light waves produced by lasers or incoherent sources for data processing, data storage or data communication for computing.For decades, photons have shown promise to enable a higher bandwidth than the electrons used in conventional computers (see optical fibers).
Sterlite Technologies Limited (formerly Sterlite Tech) [7] is an Indian optical and digital technology company, headquartered in Pune. It is listed on Bombay Stock Exchange and National Stock Exchange of India. It has 636 [8] patents and is active in over 150 countries.
5D optical data storage (also branded as Superman memory crystal, [1] a reference to the Kryptonian memory crystals from the Superman franchise) is an experimental nanostructured glass for permanently recording digital data using a femtosecond laser writing process. [2]
Jiuzhang (Chinese: 九章) is the first photonic quantum computer to claim quantum supremacy.Previously quantum supremacy has been achieved only once in 2019 by Google's Sycamore, however Google's computer was based on superconducting materials, and not photons.
An instrument which implements this approach may be described as a multivariate optical computer. Since it describes an approach, rather than any specific wavelength range, multivariate optical computers may be built using a variety of different instruments (including Fourier Transform Infrared ( FTIR ) [ 1 ] and Raman [ 2 ] ).
An optical mouse is a computer mouse which uses a light source, typically a light-emitting diode (LED), and a light detector, such as an array of photodiodes, to detect movement relative to a surface. Variations of the optical mouse have largely replaced the older mechanical mouse design, which uses moving parts to sense motion.
The IEEE Photonics Society, formerly the IEEE Lasers and Electro-Optics Society (LEOS), is a society of the Institute of Electrical and Electronics Engineers (IEEE), focused on the scientific and engineering knowledge about the field of quantum electronics.
A number of release dates were announced, all since passed, [6] likely due to actual high costs of the drives and discs itself, lack of compatibility with existing or new standards, and competition from more established optical disc Blu-ray and video streaming.
