英文摘要 | PURPOSE:To reduce reflected returned beam noises by forming a region, into which ions IIA are implanted and in which a change into the mixed crystal of a superlattice is generated through heat treatment, and a means, through which currents are constricted mainly to another region close to the region, to a superlattice layer in the vicinity of an active layer for a semiconductor laser. CONSTITUTION:An N-type Ga0.5Al0.5As clad layer 16, a GaAs/GIlAs multiple quantum well type laser active layer 15, a superlattice optical absorption layer 16, a P-type Ga0.5Al0.5As clad layer 18 and an N-type GaAs cap layer 19 are grown on an N-type GaAs substrate 13, and a P-type Ga0.3Al0.7As clad layer is shaped between the layer 15 and the layer 16. F ions are implanted to a region 24 as a mask M1 for implanting ions, and Mg ions are implanted at the same acceleration voltage. The mask M1 is removed and a mask is formed anew and F ions are implanted, and the mask is removed and the whole is annealed in an As atmosphere. Since a crystal-mixing region 17 is 50mum wide and a P region 20 is 3mum wide in a section B, a laser displays the same operation as a narrow stripe type laser, and constricts currents. Accordingly, the excellent laser resisting noises due to reflected returned beams is obtained. |
