Investigation of optical neuro-computing system based on organic photochromism

As a system, which put the optical neuro-computing into practice, a novel a rchitecture based on organic photochromism was described, The performance o f the system was examined concretely by means of computer simulation. Based on the result, a prototype system was constructed using a bulk amorphous t hin film of diarylethene to prove the feasibility of the architecture. Usin g the prototype, preliminary experiment was carried out to confirm the func tion of optical data inscription and parallel analog operation. New concept of data processing device was also suggested from the discussion over the characteristics of the system.
