| 英文摘要 | PURPOSE:To stabilize an oscillating mode at the high output operation time, to improve the differentiating efficiency and to stabilize to be adapted to environmental temperatures by continuously forming a coupling of an exciting region of a narrow waveguide width and a wide window region of a waveguide width in a coupling region that the waveguide width is varied in a tapered shape. CONSTITUTION:Window regions 22, 22' having a width Wg2, lengths Lw, Lw' are arranged at both ends of a laser oscillating region 21 having a width Wg1 and a length Le, and tapered couplers 23, 23' having lengths LT, LT' are coupled between the both regions 22, 22' and the region 2 The region 21 is limited in length at the laser oscillating region end faces 25, 25', and laser beams are emitted from the resonator end faces 24, 24'. An N type GaAs current blocking layer 32 for interrupting a current is accumulated on a P type GaAs substrate 31, and striped grooves are formed on the layer 32 and the substrate 3 A P type GaAlAs clad layer 33, a GaAs or GaAlAs active layer 34, a P type GaAlAs clad layer 35, and an N type GaAs cap layer 36 are sequentially laminated thereon. Thus, only the advantages of the VSIS laser of two types of active layer bent type and active layer flat type are utilized to complement the disadvantages, and a window laser can be readily manufactured. |
