大功率垂直腔面发射激光器阵列的热优化
Thermal Optimization of High-power Vertical Cavity Surface Emitting Laser Arrays
摘要
Abstract
In this study,we designed a new parameter,the temperature impact factor,which considers the spacing between vertical-cavity surface-emitting laser(VCSEL)array units,size of the oxidation aperture,number of units,and the input current,and can be used to characterize the degree of thermal crosstalk in the array.Based on this,we designed an optimization layout algorithm for the VCSEL array and established a thermal-electric coupling model to verify the benefits of the optimized layout on temperature characteristics.Compared with the conventional layout,the temperature rise was reduced by 5%.In addition,under the condition of fixed current density and luminous area,reduction of the oxidation aperture and increasing the number of units can effectively improve the temperature characteristics of the VCSEL array.The average temperature of the 10 μm oxidation aperture was 30 K lower than that of the 30 μm oxidation aperture.The research results show that the impact of thermal crosstalk in the VCSEL array is effectively reduced and provide guidance for the design of the VCSEL array.关键词
