LED03–Modeling of multi-electrode tapered quantum-dot superluminescent diode

Forrest A. F., Cataluna M. A., Krakowski M., Bardella P.

We introduce a rate equation based numerical model suitable for the description of the wide spectral asymmetry experimentally observed at the two facets of multi-electrode tapered superluminescent diode based on Quantum Dot material. Numerical simulations carried out with this model were able to quantitatively reproduce the behavior of a two-section SLD and explain the reported […]

PD02–S-shaped waveguide-induced asymmetry between counter-propagating modes in a racetrack resonator

Giannuzzi G., Ghillino E., Bardella P.

Ongoing progress in photonic integrated circuits necessitates the integration of semiconductor ring lasers (SRLs) with high performance and predictable behavior, which can be achieved when the symmetry of the SRL, which supports both clockwise and counterclockwise beam propagation, is unbalanced through loss mechanisms inside the resonator. In this work, numerical simulations were carried out on […]
