Abstract

The heating distribution of vertical cavity surface emitting laser array (VCSEL) is analyzed. The heating source is simplified and the heat transport model is established. The Comsol Multiphysics software is used for all numerical simulations. The temperature rise is computed by changing the cell diameter and gap between the adjacent cells. Three kinds of arrays are manufactured: 4×4, 5×5 and 8×8. The power are 580, 1 440 and 2 100 mW, the corresponding power density are 115, 374 and 853 W/cm², respectively. The values of temperature rise at 4 A are 120, 58 and 38 °C, which are obtained by redshift of wavelength. The arrays made up of small size cells can effectively reduce the thermal crosstalk and improve the output power.
