OPTICAL CIRCUIT SYSTEM AND ITS CONSTITUENTS.

摘要

An optical circuit system which takes out a part of light from an optical power-supply according to at least one kind of the output voltages of an IC, board, multi-chip module, electronic element, and opto-electronic element and generates a light signal. In this system, the optical power-supply is an optical waveguide, a waveguide laser, or a waveguide optical amplifier to which light is directed, and a light reflecting part is provided at its end and/or in its intermediate part. There is formed a signal transmission waveguide which is in contact with the side and/or the upper and lower faces of the optical waveguide or which is closely located to the optical waveguide at an interval. Thus, optical signals corresponding to at least one kind of an IC, board, multi-chip module, electronic element, and opto-electronic element are propagated in the signal transmission waveguide. This optical circuit system and the constituents have sufficient flexibilities and meet complicated optical interconnection.
