基于非对称波导结构的1.06 μm长腔半导体激光器特性分析
Characteristic analysis of 1.06 μm long-cavity diode lasers based on asymmetric waveguide structures
摘要
Abstract
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.关键词
