PROBLEM TO BE SOLVED: To realize an optical interconnection, connecting CMOS transistor LSIs at a high speed by driving CMOS transistor at a high speed. SOLUTION: Two floating type semiconductor laser structure elements or lateral junction type semiconductor laser structure elements, having an electrode divided into a plurality of sections, are employed. A set of diodes 21, 31 and 23, 33 of respective semiconductor laser structure elements are applied sequentially with a forward bias, so that they function as an optical amplifier. Another set of diodes 22, 32 and 24, 34 of respective semiconductor laser structure elements are applied with a bias and connected, to be used as photodetectors. Two photodetectors are connected to function as a differential detector, and the output of the differential detector is connected with the input gate of a CMOS transistor 9. A high absorption region 35 is provided at a part so that laser oscillation will not take place, even if a high current is fed to the optical amplifier. |
