PROBLEM TO BE SOLVED: To provide an optical pumping beam semiconductor device, which needs only few manufacturing cost as much as possible, and to provide its manufacturing method. SOLUTION: The semiconductor device has at least one emission region, to which quantum-well texture is optically pumped, and at least one pumping region. The quantum well texture and active pumping layer are extended therethrough the pump and the emission regions of the semiconductor device. The pumping beam is constituted so that it is arranged in the input-connected manner, inside the emission region in the transverse direction. COPYRIGHT: (C)2005,JPO&NCIPI |
