Samenvatting
We investigate the wavelength switching speed in
semiconductor lasers that are wavelength tunable based on
filtered optical feedback. The feedback section consists of two
arrayed-waveguide gratings and four semiconductor optical amplifiers.
The wavelength tuning and switching is controlled by
changing the currents injected in the semiconductor optical
amplifiers. We achieve a few nanoseconds wavelength switching
speed. We also investigate how this switching speed depends on
the phase and the amplitude of the feedback. We compare the
experimental observations with numerical simulations based on
a rate-equations model, from which we can identify the most
important parameters that influence the switching speed.
