Numerical Investigation of Direct Pumping of Quantum Dots in a Quantum Dot Laser

In the present paper, generalized rate equations governing a quantum dot photonic crystal nanocavity laser is used to numerically investigate the steady-state and transient behaviors of the laser. It is shown that the equations are capable of reconstructing laser behavior by direct pumping of quantum dots as well as by direct pumping of wetting layer. Numerical calculations show that the laser with direct pumping of quantum dots has much lower threshold current in comparison with direct coupling of wetting layer.
