英文摘要 | PURPOSE:To obtain a curved surface resonator semiconductor laser having a smooth face by forming the end of a plurality of flat faces, and heat treating a photoresist mask of shape having an angle formed by crossing the flat faces under specific conditions. CONSTITUTION:A photoresist mask 15 for forming a curved facelike end face is formed in advance on a semiconductor laser substrate 13 formed of a first AlGaAs clad layer 9 laminated on an N-type GaAs substrate 8, a GaAs active layer 10, a second AlGaAs clad layer 11 and an N-type GaAs cap layer 12. The mask 15 covers an electrode 14 formed insularly. The mask is heated at 120-150 deg.C for 20min-1hour. Then, it is reactive ion beam etched to form a perpendicular groove 2 Thereafter, after the mask 15 is removed by an oxygen ashing method, a rear face electrode 13 is attached, thereby obtaining a curved surface resonator laser. The mask 15 covers an insular electrode 14. The mask is heated at 120-150 deg.C for 20min to 1hr to form a vertical groove 2 After the mask 15 is removed by oxyde asking, a rear electrode 23 is provided to form a curved surface resonator laser. |
