Abstract: PURPOSE: To make it possible to perform coupling of two-dimensional semiconductor lasers by receiving the radiation leaked from the first resonant optical waveguide by the second resonant optical waveguide on a substrate, and emitting light from the first and second resonant optical waveguides substantially in synchronism with each other. CONSTITUTION: First and second array cells 48 and 50 are aligned in straight line and third and fourth array cells 52 and 54 are aligned in straight line to each other, and a diamond shape is formed. Mirrors 56, 58 and 60 at 90 degrees and 45 degrees are formed at respective one end of the respective array cells 48 and 54 formed int the diamond shape. Then, the radiation leaked from the array cell 48 hits the array cells 52 and 54, and the radiation leaked from the facing sides of the array cells 52 and 54 hits the array cell 50. Thus, only coupled cells between the different array cells emit light in complete synchronization. Therefore, the output voltage of the two-dimensional semiconductor layer can be increased, and the coupling of a plurality of the array cells can be readily performed.
