Spectral signatures of exceptional points and bifurcations in the fundamental active photonic dimer
Spectral signatures of exceptional points and bifurcations in the fundamental active photonic dimer
The fundamental active photonic dimer consisting of two coupled quantum well lasers is investigated in the context of the rate-equation model. Spectral transition properties and exceptional points are shown to occur under general conditions, not restricted by parity-time symmetry as in coupled-mode models, suggesting a paradigm shift in the field …
