Abstract
An integrated device and package 3D model is developed to computationally investigate the thermal crosstalk in arrays of proton-implanted top-surface emitting lasers. A self- consistent electro-thermo-opto model is employed for the device. The anisotropic thermal property is considered for the package model. Temperature dependency of critical device and material properties is included, as well as multiple heat generation mechanisms. Effects of spacing on lasing performance and non-uniformity of VCSEL arrays are found significant. Thermal crosstalk becomes worse for increased sizes and packaging densities of laser arrays. Degraded laser performance is found due to the thermal crosstalk, especially for the lasers closest to the center of the array package.
