Polarization properties in the transition from below to above lasing threshold in broad-area vertical-cavity surface-emitting lasers

M. Schulz-Ruhtenberg, I. V. Babushkin, N. A. Loiko +2

For highly divergent emission of broad-area vertical-cavity surface-emitting lasers (VCSELs) a rotation of the polarization direction by up to 90 degrees occurs when the pump rate…

Scar-like structures and non-integrability in a perfectly square optical billiard

I. Babushkin

We show that scar-like structures (SLS) in a wide aperture vertical cavity surface emitting laser (VCSEL) can be formed even in a perfectly square geometry due to interaction of po…
