Dynamics of Linewidth-Enhancement Factor in Semiconductor Optical Amplifiers

Not Accessible

Your library or personal account may give you access


It is shown that the linewidth-enhancement α-factor in a semiconductor optical amplifier (SOA) has a significant temporal dependence. A time window with a small or even a negative α-factor is observed both in experiments and in calculations. This observation might seriously impact the performance of XPM devices at highest speed.
