ABSTRACT:
The opto-electronic integrated circuit device comprises an optical switch18provided in an input port12aof a first input/output port36aover a substrate10and changing over an optical path of an optical signal inputted from the input port12aand outputting the optical signal through one of a plurality of output terminals24a–24d;an opto-electric conversion element26aoptically connected to one of the plural output terminals of the optical switch18,and converting the optical signal outputted from one of the output terminals24a–24dof the optical switch18to an electric signal and inputting the converted electric signal in a semiconductor element30mounted over the substrate10;and an optical waveguide50optically connected to another of the plural output terminal24dof the optical switch18and outputting the optical signal outputted from said another output terminal24dof the optical switch18through an output port32bof a second input/output port36bover the substrate10.
