Improved Temperature Characteristics in Quantum Dot Lasers with Indirect-Bandgap Barriers
Abstract
This study demonstrates that a much high characteristic- temperature can be achieved with quantum dot lasers of indirect barrier compared to those of direct barrier. The temperature dependence of threshold current is reduced because the injected carriers residing in the barrier at high temperatures recombine slowly.
