Abstract
A method of forming waveguides, refractive index distributions and optical couplings automatically by light incidence, and devices obtained thereby. A non-linear optical material which has excellent properties of a large degree of freedom for an optical circuit substrate composition, etc. is used for optical circuit devices and optical circuit substrates. A photoelectric device containing an organic conjugated polymer film is deposited on a substrate by vapor deposition polymerization as at least one function layer. An optical network is provided with optical wiring for exchanging signals between processing elements selected from electronic elements, electronic apparatuses, electrooptical elements and electrooptical apparatuses.
