Spontaneous emission induced filamentation in flared amplifiers

We present a propagation model for the steady-state properties of InGaAs QW flared laser amplifiers. Included in this analysis are diffusion, diffraction, carrier induced antiguiding, current spreading, gain spatial hole burning, gain compression and spontaneous emission. By monitoring the progress...
