Transform1
However, any electromagnetic wave must obey the transform limit, and therefore the rate at which an optical transistor can respond to a signal is still limited by its spectral bandwidth. (wikipedia.org)
Equivalent3
To replace electronic components with optical ones, an equivalent optical transistor is required. (wikipedia.org)
The prototype achieves a processing speed equivalent to 320 Gigaflops and, because it uses light rather than electricity as the processing medium, it is much more energy efficient than classical processing devices. (insidehpc.com)
According to the chairman of the company, James Duez, Optalysys's initial products will launch in 2017 and he expects them to achieve HPC-levels of performance up to an equivalent processing rate of 9 petaflops. (insidehpc.com)

Switching is obtained using nonlinear optical effects when two or more signals are combined. (wikipedia.org)
Computer3
Most research projects focus on replacing current computer components with optical equivalents, resulting in an optical digital computer system processing binary data. (wikipedia.org)
This may result in the processing elements for an optical computer requiring more power and larger dimensions than those for a conventional electronic computer using transistors. (wikipedia.org)
Though some groups are using spatial light modulators for AI, they represent just one category of optical computer suitable for the job. (acm.org)

System3
Like any computing system, an optical computing system needs three things to function well: optical processor optical data transfer, e.g. fiber-optic cable optical storage, Substituting electrical components will need data format conversion from photons to electrons, which will make the system slower. (wikipedia.org)
Optalysys , a start-up company based in Cambridge England, has announced that, starting next month, its prototype optical processing system will be used in large-scale DNA sequence searches, saving up to 95 per cent of energy costs compared to conventional electronic methods, the company claims.
