Relaxation Oscillations in the Gain Recovery of Gain-Clamped Semiconductor Optical Amplifiers: Simulation and Experiments

Not Accessible

Your library or personal account may give you access


This paper shows experimental data and simulation results of the gain recovery of gain-clamped semiconductor optical amplifiers (GC-SOA). Damped relaxation oscillations are observed. Both the oscillation frequency and damping rate increase with applied current and can attain very high values. We measured a gain recovery time of 26 ps at 200 mA applied current and an oscillation frequency of 11 GHz. A good agreement between experimental data and simulation results is obtained. Simulation results indicate that a GC-SOA used as amplifier in wavelength division multiplexing (WDM) networks can amplify signals at very high bit-rates with low cross-talk and extinction ratio compression.
