摘 要:Absorption induced by activated magnesium(Mg)in a p-type layer contributes considerable optical internal loss in Ga Nbased laser diodes(LDs).An LD structure with a distributed polarization doping(DPD)p-cladding layer(CL)without intentional Mg doping was designed and fabricated.The influence of the anti-waveguide structure on optical confinement was studied by optical simulation.The threshold current density,slope efficiency of LDs with DPD p-CL,and Mg-doped CL,respectively,were compared.It was found that LDs with DPD p-CL showed lower threshold current density but reduced slope efficiency,which were caused by decreasing internal loss and hole injection,respectively.
关 键 词:polarization doping internal loss GaN laser diode
