Numerical analysis of gain-switched quantum dot lasers

Theoretical analysis of gain-switched quantum dot lasers is done using a multi-population rate equations based model. In particular, we investigate the emission spectrum dependence on both the driving current bias level and on the repetition rate of the pulse train. Results show that these two param...

Zusammenfassung:Theoretical analysis of gain-switched quantum dot lasers is done using a multi-population rate equations based model. In particular, we investigate the emission spectrum dependence on both the driving current bias level and on the repetition rate of the pulse train. Results show that these two parameters can be suitably handled to yield only-ground state, only-excited state or even both ground and excited state emission.
