TL;DR: The concept of optical rogue wave was introduced by Solli et al. as discussed by the authors, who defined it as "an optical pulse whose amplitude or intensity is much higher than that of the surrounding pulses".
Journal ArticleDOI
Deterministic polarization chaos from a laser diode
Martin Virte,Martin Virte,Krassimir Panajotov,Krassimir Panajotov,Hugo Thienpont,Marc Sciamanna +5 more
TL;DR: In this paper, the polarization of the output from a vertical-cavity surface emitting laser without the need for any external stimulus or feedback has been observed, and the origin is nonlinear coupling between two elliptically polarized modes within the device.
Journal ArticleDOI
PlaneWave Admittance Method — a novel approach for determining the electromagnetic modes in photonic structures
TL;DR: A novel approach for determining the electromagnetic modes of photonic multilayer structures is presented which combines the plane wave expansion method with the method of lines resulting in a fast and accurate computational technique which is named plane wave admittance method.
Journal ArticleDOI
Polarization switching in VCSEL's due to thermal lensing
Krassimir Panajotov,B. S. Ryvkin,Jan Danckaert,Michael Peeters,Hugo Thienpont,Irina Veretennicoff +5 more
TL;DR: In this article, a mechanism for polarization switching in slightly anisotropic vertical-cavity surface-emitting lasers (VCSELs) based on index guiding due to the effect of thermal lensing was demonstrated.
Journal ArticleDOI
Optical feedback induces polarization mode hopping in vertical-cavity surface-emitting lasers.
Marc Sciamanna,Krassimir Panajotov,Hugo Thienpont,Irina Veretennicoff,Patrice Mégret,Michel Blondel +5 more
TL;DR: Vertical-cavity surface-emitting lasers subjected to weak polarization-insensitive optical feedback are studied experimentally and theoretically and it is found that the feedback induces random anticorrelated hopping between the two orthogonal linearly polarized modes.
