波导/势垒界面插入GaInP和GaAsP对InAlGaAs量子阱808-nm激光二极管载流子泄漏的影响
Effect of GaInP and GaAsP inserted into waveguide/barrier interface on carrier leakage in InAlGaAs quantum well 808-nm laser diode
摘要
Abstract
There is nonradiative recombination in waveguide region owing to severe carrier leakage,which in turn reduces output power and wall-plug efficiency.In this paper,we designed a novel epitaxial structure,which suppresses carrier leakage by inserting n-Ga0.55In0.45P and p-GaAs0.6P0.4 between barriers and wave-guide layers,respectively,to modulate the energy band structure and to increase the height of barrier.The results show that the leakage current density reduces by 87.71％,compared to traditional structure.The non-radiative recombination current density of novel structure reduces to 37.411 A/cm2,and the output power reaches 12.80 W with wall-plug efficiency of 78.24％at an injection current density 5 A/cm2 at room temper-ature.In addition,the temperature drift coefficient of center wavelength is 0.206 nm/℃ at the temperature range from 5 ℃ to 65 ℃,and the slope of fitted straight line of threshold current with temperature variation is 0.00113.The novel epitaxial structure provides a theoretical basis for achieving high-power laser diode.关键词
