| 英文摘要 | PURPOSE:To inhibit oscillation in a Fabry-Perot mode by forming an air gap to at least one side of the projected surface sides of beams so that the length of a light-emitting layer is made shorter than the length of an adjacent layer. CONSTITUTION:In the distribution feedback type semiconductor laser consisting of an N type InP substrate 1, an N type InGaP waveguide layer 2, the InGaAsP light-emitting layer 3, an InGaAsP buffer layer 4, a P type InP layer 5, a P type InGaAsP layer 6 and electrodes 7, the air gap 10 is formed to at least one side of the projected surface 9 sides of beams so that the length of the light- emitting layer 3 is made shorter than the length of the adjacent layers 2, 4. Beams change into a state that they are radiated from the air gap 10 form a state that they are confined to the light-emitting layer 3, and oscillation threshold value to the Fabry-Perot mode can be increased remarkably. |
