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

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 spectral asymmetry in terms of non-uniform filling of the QD confined states under non-uniform current injection.
