Abstract
The performance of InP/InAs quantum dash (QDash) and quantum dot (QDot) multi-wavelength lasers, using identical structural design, are investigated and compared to each other. The QDash lasers show a lower threshold current and cavity loss. On the other hand, the QDot lasers show higher internal quantum efficiency, as well as lower average integrated relative intensity noise (RIN) and average optical linewidth. This finding highlights the viability of InAs/InP QDash/QDot lasers to be used as a low-cost optical source for large-scale networks.
