Summary
How does self-heating affect phase-coupled VCSEL-array operation?
Models heat sources and the connection between temperature, thermal lensing and optical modes.
Shows why thermal behaviour belongs in the analysis of high-power arrays.

Commentary
Results depend on thermal parameters, interfaces, contacts and the specific array geometry.
An optical design is only one part of a powered device; temperature feeds back into the cavity.
