Implementing an insect brain computational circuit using III-V nanowire components in a single shared waveguide optical network
David O. Winge, Steven Limpert, Heiner Linke +4
Recent developments in photonics include efficient nanoscale optoelectronic components and novel methods for sub-wavelength light manipulation. Here, we explore the potential offer…
Domain formation and self-sustained oscillations in quantum cascade lasers
Tim Almqvist, David O. Winge, Emmanuel Dupont +1
We study oscillations in quantum cascade lasers due to traveling electric field domains, which are observed both in simulations and experiments. These oscillations occur in a range…
Ignition of quantum cascade lasers in a state of oscillating electric field domains
David O. Winge, Emmanuel Dupont, Andreas Wacker
Quantum Cascade Lasers (QCLs) are generally designed to avoid negative differential conductivity (NDC) in the vicinity of the operation point in order to prevent instabilities. We…
Simple electron-electron scattering in non-equilibrium Green's function simulations
David O. Winge, Martin Franckié, Claudio Verdozzi +2
In this work we include electron-electron interaction beyond Hartree-Fock level in our non-equilibrium Green's function approach by a crude form of GW through the Single Plasmon Po…
Nonlinear response of quantum cascade structures
David O. Winge, Martin Lindskog, Andreas Wacker
The gain spectrum of a terahertz quantum cascade laser is analysed by a non equilibrium Green's functions approach. Higher harmonics of the response function were retrievable, prov…
