Low threshold InAs/InP quantum dot lasers on Si
We have developed low threshold InP-based L-band quantum (QD) lasers monolithically grown on Si substrates for photonic integration. To overcome the fundamental challenges of growing high-density, high uniformity QDs on InP-based material system, QD thickness in combination with a modified indium flush technique was adopted, resulting in a low threshold current density of 1.35 kA/cm<sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> and pulsed lasing up to 100 °C. These results represent progress in C-/L-band QD laser development on Si, highlighting the potential for high-performance semiconductor light source for long-haul telecommunication applications.
