Comprehensive modelling of resonant-cavity light-emitting diode

We extended the theory by Henry (J. Lightwave Technol. LT-4, 288 (1986) [1]) to accurately treat the coupling of spontaneous emission noise with microcavity modes. The Green's function method is employed to solve the inhomogeneous wave equation including a Langevin force F. which accounts for spontaneous emission by carriers at angular frequency omega. The optical wave equation is coupled with the self-consistent calculations of the material spontaneous emission rate of quantum well-dot using envelope wavefunction method. Finally the carrier transport equations are solved within the framework of 2D/3D drift-diffusion model implemented in the Crosslight Software package APSYS (Crosslight APSYS User's Manuals, Copyright Crosslight Software Inc.
