Excitability in optical systems close to Z2-symmetry

Beri, S.; mashal, L.; Gelens, L.; Van der Sande, G.; Verschaffelt, G.; Danckaert, J. (North-Holland, 2010-01-18)

We report theoretically and experimentally on excitability in semiconductor ring lasers in order to reveal a mechanism of excitability, general for systems close to Z 2-symmetry. The global shapes of the invariant manifolds ...
Excitability in semiconductor microring lasers: Experimental and theoretical pulse characterization

Gelensl, L.; mashal, L. (Phys. Rev. A, 2010)

We characterize the operation of semiconductor microring lasers in an excitable regime. Our experiments reveal a statistical distribution of the characteristics of noise-triggered optical pulses that is not observed in ...
Low-frequency fluctuations in semiconductor ring lasers with optical feedback

Mashal, L. (IEEE J. Quantum Electron, 2013)

In this paper, we experimentally and numerically study the dynamics of semiconductor ring lasers that are subjected to long delay and moderate self-feedback. Through varying the pump current or the feedback strength or ...
Semiconductor ring lasers as optical neurons

Mashal, L. (International Society for Optics and Photonics, 2012)

Semiconductor Ring Lasers (SRLs) are a modern class of semiconductor lasers whose active cavity is characterized by a circular geometry. This enables the laser to support two counterpropagating modes, referred to as the ...
