| 英文摘要 | The vertical divergence angle of GaAs-based laser diodes (LD) can be reduced by usually increasing waveguide thickness and inserting low index layers between waveguide layers and cladding layers, but it will also induce an increase of the threshold current. It is proposed to make the inserted low index interlayers doped and asymmetric to simultaneously reduce vertical divergence angle and alleviate the deterioration of threshold current. The simulation results indicate that the carrier leakage and injection are improved due to the change of energy band profile. The characteristics of newly designed laser structure indicate a satisfactory light beam quality and a relatively low threshold current density. (C) 2015 Elsevier Ltd. All rights reserved. |
