dc.description.abstract
Semiconductor optical amplifiers (SOAs) have found widespread use in
optical communications covering the important telecommunications window
with optical carrier wavelengths from 1.1 μm up to 1.6 μm. While amplifiers
are usually operated in their linear region, the inherent nonlinearities of
SOAs can be exploited for all-optical signal processing like signal
regeneration, wavelength conversion, and modulation format conversion. For
both, linear and nonlinear applications, the onset and the amount of the
nonlinear response is important for choosing the proper operating point.
In this book a nonlinear SOA model is developed. Measuring the spectra
resulting from a pump-probe experiment, the strength of the various
nonlinear contributions can be assigned to inter- and intraband carrier
dynamics in the semiconductor. The experiments reveal for the first time the
importance and the role of two-photon induced free carrier absorption
FCATPA – an effect that so far was not properly taken care of. The resulting
blue-shifted sideband makes it possible to design a patterning-free all-optical
wavelength converter. More generally, this model helps in finding optimal
optical filter schemes for wavelength converters, resulting in patterning-free
output signals at high bit rates.
