| Abstract | Quantum dot lasers containing five stacked layers of InAs quantum dots (QDs) embedded in quaternary InGaAsP are grown on [100] InP substrates. The QD ensemble has a density of 1.5 × 1010 cm-2 and emits light at ∼1.6 μm at 77 K. Lasing wavelength and threshold current density can be shifted by changing the cavity length of the laser diode and the latter reaches a value as low as 49 A/cm2 at 77 K for a gate size of 2000 μm × 150 μm. Temperature dependence of the threshold current is observed implying the presence of thermionic emission increasing with temperature. |
