Summary
How do noncircular VCSEL cavities change emission?
Studies cavity geometries experimentally and uses 3D passive FEM mode calculations for interpretation.
Connects geometry to mode distributions, beam patterns and gain utilization.

Commentary
The passive numerical model uses representative sizes and does not independently reproduce all active-device physics.
An example of finite-geometry modelling where a single periodic unit cell is not sufficient.
