Opto-electronic integrated circuit device, opto-electronic integrated circuit system and transmission method

摘要

The opto-electronic integrated circuit device comprises an optical switch 18 provided in an input port 12 a of a first input/output port 36 a over a substrate 10 and changing over an optical path of an optical signal inputted from the input port 12 a and outputting the optical signal through one of a plurality of output terminals 24 a- 24 d; an opto-electric conversion element 26 a optically connected to one of the plural output terminals of the optical switch 18, and converting the optical signal outputted from one of the output terminals 24 a- 24 d of the optical switch 18 to an electric signal and inputting the converted electric signal in a semiconductor element 30 mounted over the substrate 10; and an optical waveguide 50 optically connected to another of the plural output terminal 24 d of the optical switch 18 and outputting the optical signal outputted from said another output terminal 24 d of the optical switch 18 through an output port 32 b of a second input/output port 36 b over the substrate 10.
