Later, data is sent through the fibre optic cables depending on its final location. The holographic
memory receives some information, where it will then be saved. Saved information is accessed
by the program that requires it by sending a command to the central processing unit. As soon as
the information is received by the program, information is again sent to the processor to notify
that the task was successfully received (Athale & Psaltis, 2016, p.32).
In addition, optic computers performance will entail: an optical processor, optical data transfer,
for instance, a fibre optic cable and an optical storage like a CD or DVD. According to Xiao,
Xue & Hui, (2016, p.053103), a critical analysis indicates that the use of photons or light is made
in logic gates present in a computer. An emphasis is also made on the switching mode of the
logic gates which is achieved using nonlinear optical effects as signals are combined. Moreover,
Resonators are also used which enable energy build up from constructive interference hence
promoting optical nonlinear effects (Xiao, Xue & Hui, 2016, p.053103).
The Future of Optical Computers
While optical computers still dominate, numerous advancements about their future are emerging
that will translate for their better performance (Xiao, Xue & Hui, 2016, p.053103). Among the
advancements is that the optic computers will utilize crystals and metamaterials to control light,
the introduction of signal processing and frequency doubling under minimum power usage.
Hence, through these, super fast and lightweight systems will be developed (Computers &
Security Editorial Board, 2018, p. iii).
