Abstract :
A synthesis is made of the optical model for a quantum well (QW) and a quantum dot (QD) laser using Fermi golden rule and the electrical model based on continuity equation for a Transistor Laser. The calculated values of threshold base current and light power for InGaAs QW embedded in GaAs base agree with the experimental value. The predicted threshold base current for Quantum Dots is an order of magnitude lower.
