Abstract
An optical circuit device is manufactured by forming an organic film formed on a substrate, and giving this organic film non-linear optical properties. An optical circuit device is formed containing an organic film formed on a substrate, wherein said film is either selectively formed on a portion of the region on a substrate or said film being formed over the entire region on a substrate, and a portion of a region of that film is either selectively formed to a thickness differing from other regions or selectively having a different structure. This optical circuit device can be manufactured to have various constitutions, and allows the formation of a multilayer optical circuit.
