Oscillations and multistability in two semiconductor ring lasers coupled by a single waveguide

by Coomans, W., Van der Sande, G. and Gelens, L.
Abstract:
We theoretically study the dynamical behavior of semiconductor ring lasers coupled by a single bus waveguide, both when weakly coupled and when strongly coupled. We provide a detailed analysis of the multistable landscape in the coupled system, analyze the stability of all solutions, and relate the internal dynamics in the individual lasers to the field effectively measured at the output of the waveguide. We show that coupling phases close to π/2 generally promote instabilities. Finally, our analysis enables us to discuss the advantages and disadvantages for optical memory operation of coupled semiconductor ring lasers versus solitary ones.
