Abstract
The influence of heating on the eigenmodes of a semiconductor laser is studied, using finite elements to solve for the transverse temperatur e distribution and the eigenmode, and assuming a first order variation of the material index with temperature. Besides the expected increase of the effective index, a self-focusing effect leading to beam-narrow ing and an increase of the confinement factor (which can change by as much as 10%) is evidenced.
