  tunnel-injection semiconductor lasers   Tunnel-injection lasers promise various advantages in comparison to
conventional laser designs. In this paper, we present a theoretical analysis
for the physics of the tunnel-injection process in quantum-dot based laser
devices. We describe the carrier dynamics in terms of scattering between states
of the coupled system consisting of injector quantum-well, tunnel-barrier, and
quantum-dots. Our analysis demonstrates how current quantum-dot based lasers
can benefit from the tunnel-injection design. We find that the often assumed
LO-phonon resonance condition for the level alignment only weakly influences
the injection rate of carriers into the quantum-dot states. On the other hand,
our investigations show that the energetic alignment of quantum-dot and
quantum-well states modifies the injection efficiency, as it controls the
hybridization strength. Our description of tunneling includes the
phonon-mediated and the Coulomb scattering contributions and is based on
material realistic electronic structure calculations.
