Dispersion-induced dynamics of coupled modes in a semiconductor laser with saturable absorption
Finbarr O'Callaghan, Simon Osborne, Stephen O'Brien
We present an experimental and theoretical study of modal nonlinear dynamics in a specially designed dual-mode semiconductor Fabry-Perot laser with a saturable absorber. At zero bi…
Design optimization of passively mode-locked semiconductor lasers with intracavity grating spectral filters
Finbarr O'Callaghan, David Bitauld, Stephen O'Brien
We consider design optimization of passively mode-locked two-section semiconductor lasers that incorporate intracavity grating spectral filters. Our goal is to develop a method for…
Multi-stabilities and symmetry-broken one-colour and two-colour states in closely coupled single-mode lasers
Eoin Clerkin, Stephen O'Brien, Andreas Amann
We theoretically investigate the dynamics of two mutually coupled identical single-mode semi-conductor lasers. For small separation and large coupling between the lasers, symmetry-…
Bursting: when a cusp and a pitchfork interact
Nicholas Blackbeard, Simon Osborne, Stephen O'Brien +1
We present an experimental and theoretical study of an unusual bursting mechanism in a two-mode semiconductor laser with single-mode optical injection. By tuning the strength and f…
Bistability and all-optical memory in dual-mode diode lasers with time-delayed optical feedback
N. Brandonisio, P. Heinricht, S. Osborne +2
A proposal for an all-optical memory based on a bistability of single-mode states in a dual-mode diode laser with time-delayed optical feedback is presented. The system is modeled…
Timing characterization of 100 GHz passively mode-locked discrete mode laser diodes
David Bitauld, Simon Osborne, Stephen O'Brien
We report on the characterization of the timing stability of passively mode-locked discrete mode diode laser sources. These are edge-emitting devices with a spatially varying refra…
