| 英文摘要 | An edge emitting semiconductor laser suppresses the “beam steering” to raise its maximum output with a simple configuration. An optical waveguide serving as a resonator includes an active layer and a cladding layer. A first edge, to which one end of the waveguide is connected, serves as an emission edge. A second edge, to which the other end of the waveguide is connected, is located at an opposite side to the first edge. The waveguide includes at least two parts having different widths, one of the at least two parts being a fundamental mode section. Current injection suppressing means is provided for suppressing or controlling current injection into the active layer in at least part of the fundamental mode section. The current injection suppressing means is preferably made by a current blocking layer, a current-limiting masking layer, or a passive wave-guiding region. |
