Abstract
Optics is already penetrating the field of digital computing for example as read-only storage, as bus and as I/O devices. Protection against E.M.I. and E.M.P. is an incentive for replacing electronics by optics. Another incentive is the speed potential based on a carrier frequency of a million GHz.
Yet another incentive is the superior communications topology of optics: many light rays can criss-cross each other without disturbances. For comparison: only one wire can occupy any particular part of the three-dimensional space.
The specific projects at Erlangen deal with optics in conventional computers as well as with all optical computers.
