英文摘要 | PURPOSE:To faciliate monolithic integration be a method wherein a plurality of lasers with double-hetero structures containing active layers are formed on a semiconductor substrate and the thickness of end plane reflection coatings on the cavity planes of one side are made different for the respective lasers. CONSTITUTION:A P-type GaAs buffer layer 7, a P-type AlGaAs cladding layer 6, an AlGaAs active layer 5, an N-type AlGaAs cladding layer 4, an N-type GaAs cap layer 3 and an AlGaAs isolation layer 2 are successively grown on a conductive P-type GaAs substrate 8. Then, stripe structures are formed in the AlGaAs isolation layer 2 by chemical etching. In this state, electrodes 1 and 9 are formed on the N-type side and the P-type side respectively. If the substrate is cleft into array-shape and fixed to a fixing jig 11 and subjected to sputtering, the thickness of the coating film become thinner near the position where the height of the fixing jig 11 is higher. Therefore, the thickness of the coating film can be controlled by controlling the angle and the position of the jig 1 As the reflectance of the respective end planes of the lasers are different, the extra process such as changing oscillation wavelength becomes unnecessary. |
