在长腔边发射二极管激光器中,纵向空间烧孔(LSHB)、双光子吸收(TPA)和自由载流子吸收(FCA)是影响高注入电流下输出功率线性增长的关键因素.针对1.06 μm长腔半导体激光器,通过将TPA和FCA损耗与一维速率方程相结合,提出一种简化数值分析模型.系统分析了LSHB、TPA和FCA对输出特性的影响,并提出可以通过调整前腔面反射率和量子阱(QW)在波导层中的位置来提高前腔面输出功率.
Characteristic analysis of 1.06 μm long-cavity diode lasers based on asymmetric waveguide structures
In long-cavity edge-emitting diode lasers,longitudinal spatial hole burning(LSHB),two-photon ab-sorption(TPA)and free carrier absorption(FCA)are among the key factors that affect the linear increase in out-put power at high injection currents.In this paper,a simplified numerical analysis model is proposed for 1.06 μm long-cavity diode lasers by combining TPA and FCA losses with one-dimensional(1D)rate equations.The ef-fects of LSHB,TPA and FCA on the output characteristics are systematically analyzed,and it is proposed that ad-justing the front facet reflectivity and the position of the quantum well(QW)in the waveguide layer can improve the front facet output power.
