Dynamical control of non-hermitian coupling between sub-threshold nanolasers enables Q-switched pulse generation
Kristian Seegert, Roberto Gajardo, Guillaume Huyet +2
Non-Hermitian photonics provides a framework to engineer the gain and loss of optical modes in open systems, enabling control of their spectral and dynamical properties. In particu…

Instantaneous modes in dispersive laser cavities
Kristian Seegert, Yi Yu, Mikkel Heuck +2
We develop a unified instantaneous-mode description for lasers with dispersive cavities, exploiting the separation of timescales between fast cavity fields and slow carrier dynamic…

Self-pulsing dynamics in microscopic lasers with dispersive mirrors
Kristian Seegert, Mikkel Heuck, Yi Yu +2
We show that a passive dispersive reflector integrated into a semiconductor laser can be used to tailor the laser dynamics for the generation of ultrashort pulses as well as stable…
