Spatial Control of Localized Oscillations in Arrays of Coupled Laser Dimers
Joniald Shena, Yannis Kominis, Anastasios Bountis +1
Arrays of coupled semiconductor lasers are systems possessing radically complex dynamics that makes them useful for numerous applications in beam forming and beam shaping. In this…
Radically Tunable Ultrafast Photonic Oscillators via Differential Pumping
Yannis Kominis, Anastassios Bountis, Vassilios Kovanis
We present the controllability capabilities for the limit cycles of an extremely tunable photonic oscillator, consisting of two coupled semiconductor lasers. We show that this syst…
Enhanced stability, bistability, and exceptional points in saturable active photonic couplers
Yertay Zhiyenbayev, Yannis Kominis, Constantinos Valagiannopoulos +2
A generic photonic coupler with active and lossy parts, gain saturation and asymmetric characteristics is examined. Saturable activity is shown to be able to enhance the overall st…
Antiresonances and Ultrafast Resonances in a Twin Photonic Oscillator
Yannis Kominis, Kent D. Choquette, Anastasios Bountis +1
We consider the properties of the small-signal modulation response of symmetry-breaking phase-locked states of twin coupled semiconductor lasers. The extended stability and the var…
