The Fast Recovery Dynamics Of A Quantum Dot Semiconductor Optical Amplifier, T. Piwonski, Guillaume Huyet, Et. Al.

Physical Sciences Publications

We consider a rate equation model of a quantum dot semiconductor optical amplifier that takes into account carrier capture, escape, and Pauli blocking processes. We evaluate possible differences between phonon-assisted or Auger processes being dominant for recovery. An analytical solution which corresponds to phonon-assisted interaction is then used to accurately fit experimental recovery curves and allows an estimation of both the carrier capture and escape rates.
