英文摘要 | PURPOSE:To obtain a device capable of emitting in single mode, widening the emission area, and high output operation, by forming a refractive index distribution and gain distribution in the transverse direction of a wide ridge and composing so as to form a plurality of lasers adjacent to the ridge. CONSTITUTION:A semiconductor laser device comprises a semiconductor substrate 1, on which a semiconductor active layer 3, first and second semiconductor clad layers 2 and 4 mounted adjacent to and having a wider forbidden band than said active layer 3, and a third semiconductor blocking layer S having a wider forbidden band than and of a different conduction type from, and mounted on said second semiconductor clad layer 4 having a striped-looking ridge 16 of 10mum or more width are installed at least. A plurality of gain waveguide paths are formed on the ridge 18 by forming a plurality of striped- looking mesa-shaped grooves on the third semiconductor blocking layer 5 on the ridge 16, for example a n-type AlGaAs blocking layer 5 having two mesa- shaped grooves formed on a p-type AlGaAs upper clad layer 4 having an about 15mum wide ridge 16. |
