本文介绍了发射波长为1.3μm的条形InGaAsP/InP双异质结激光器的高温特性。为了估计热特性,诸如热耗散功率、热阻、四元有源层的温度增加对连续工作的影响,并推导高温下稳定工作的条件,分析了增益导引激光器和折射半导引激光器的热特性与条宽和腔长的关系。采用了质子轰击激光器和自对准激光器,研究了室温以上的振荡性能,并与分析结果进行了比较。 This article describes the high temperature characteristics of a strip InGaAsP / InP double heterostructure laser with an emission wavelength of 1.3 μm. In order to estimate the thermal characteristics such as heat dissipation power, thermal resistance, temperature increase of the quaternary active layer on the continuous operation and derive the conditions for stable operation at high temperature, the effects of the gain-guided laser and the refractive semi-guided laser Relationship between thermal characteristics and strip width and cavity length. Proton bombardment lasers and self-aligned lasers were used to study the oscillation performance above room temperature and compared with the analytical results.
