Two-dimensional arrays of vertical-cavity surface-emitting lasers (VCSELs) are very promising for use in parallel optical information processing, optical computing, high-speed and high-bandwidth free-space optical interconnects, and fibre-optic communications. However, one of the biggest problem is thermal behaviour of VCSELs, seriously limiting massive integration into 2D arrays. The paper presents an integrated sofware package for three-dimensional simulation and analysis of VCSEL arrays, allowing to investigate thier thermal, electrical and optical behaviour, as well as thermal crosstalk. Unique features of the presented softwere include full 3D thermal simulation of semiconductor laser array in package, coupled with self-consistent electro-thermo-optical model of VCSEL on a device level. Temperature dependencies of critical device and material properties are included, as well as multiple heat generation mechanisms. Computation results showing effects of spacing on lasing performance are presented. Degraded laser performance has been found due to the thermal crosstalk, which becomes more important for increased sizes and desities of laser arrays.
