A three-dimensional electrical-thermal coupling model based on the finite element method is applied to study thermal properties of implant-defined vertical cavity surface emitting laser(VCSEL) arrays.Several parameters including inter-element spacing,scales,injected current density and substrate temperature are considered.The actual temperatures obtained through experiment are in excellent agreement with the calculated results,which proves the accuracy of the model.Due to the serious thermal problem,it is essential to design arrays of low self-heating.The analysis can provide a foundation for designing VCSEL arrays in the future.
