I don't think it's a real OpenBSD question, but let me try to answer.
As far as I know there are no real (useful) optical processors yet.
A while ago there was an new company who promised the EnLight 256.
An optical processor for highly specialized tasks, but i never heard
about
the device being used.
Optical logic gates have been created in a research setting, but I
don't believe
the manufacturing process is useful for large scale production.
The real advantage of optical logic gates are in my opinion not
calculations.
This is because the gates are too large. But you could use optical
links for
communications between various components in your computer or even
between various components inside your cpu.

How far in development are CPU's that only use light as their input
and have a
series of optical logic gates to do processing? Alternatively they
have
electric inputs to power laser emitting diodes. Does something
exist yet in
the 21st century? I'd imagine it would have incredible power
savings in
operation and for cooling purposes.
