Abstract :
We generalize the photon recycling effect to include three distinctive phenomena: amplified spontaneous emission, absorption and instantaneous re-emission processes. These processes can be directly inferred from the physical phenomenon of a spontaneous emission spectrum overlapping a stimulated gain spectrum. We incorporate this generalized photon recycling model into a 2D/3D ray tracing algorithm and coupled it self-consistently to a general 2D/3D device simulator (Sentaurus DeviceTM.
