Investigations on the relative intensity noise of a two-state quantum dot laser

We investigate the spectrally-resolved relative intensity noise (RIN) of a dual state emitting quantum-dot (QD) laser in dependence on the laser biasing conditions. We study the RIN under free-running conditions as well as under external optical feedback (OFB). We find an improvement in RIN of the free-running laser when ground state (GS) and excited-state (ES) emit simultaneously as compared to a single-state emission. Furthermore, we find an improvement in RIN under external OFB.
