Physical Review A · 107, 033509

Summary

What changes when linear gain anisotropy is included in a spin-VCSEL model?

Extends the spin-flip model and studies polarization dynamics near exceptional points.

Predicts helicity switching and frequency-comb generation without external injection locking.

Commentary

These are model predictions, not an experimental demonstration of all proposed operating regimes.

A direct bridge from anisotropic propagation to nonlinear dynamics, with several collaborators from the thesis research.
